Christopher Brian Bridges (born September 11, 1977), better known by his stage name Ludacris, is an American rapper and actor. Along with his manager, Chaka Zulu, Ludacris is the co-founder of Disturbing tha Peace, an imprint distributed by Def Jam Recordings. Ludacris has won the Screen Actors Guild, Critic's Choice, MTV, and Grammy Awards during his career.

Ludacris was born Christopher Brian Bridges in Champaign, Illinois. He is of African American and Native American descent. Bridges wrote his first rap song at age nine when moving to Atlanta and joined an amateur rap group three years later. He attended Banneker High School in Atlanta, Georgia. From 1998 to 1999, he studied music management at Georgia State University. In Feb. 2007, Bridges lost his father, Wayne, to cancer. Ludacris has a daughter named Karma with an Atlanta attorney named Christine White.

Ludacris collaborated with Timbaland on the track "Phat Rabbit" from his album Tim's Bio: Life from da Bassment. Is it later included on Ludacris's debut LP album Back for the First Time.

Ludacris released his major label debut, Back for the First Time, in October 2000. This album was actually a modified re-release of the album Incognegro, made in 1998. It was produced with the help of the underground producer Sessy Melia, whom he dated for a short while. The album reached as high as #4 on the U.S. Billboard 200, and was a major success. Ludacris made his mark on the industry with singles such as "Southern Hospitality" and "What's Your Fantasy", along with his first ever single the "Phat Rabbit", from two years prior. Guest appearances included 4-Ize, I-20, Shawnna, Pastor Troy, Timbaland, Trina, Foxy Brown, UGK, and others. Ludacris stated in an interview on MTV's hip hop program Direct Effect that he came up with his stage name based on his "split personality" that he considered "ridiculous" and "ludicrous".

Ludacris promptly completed his next album, Word of Mouf, and released it at the end of 2001. The video for the lead single, "Rollout (My Business)", was nominated for a 2002 VMA, and Ludacris performed it live at the awards' pre-show. He released singles "Saturday (Oooh Oooh)" with Sleepy Brown, "Move Bitch" with Mystikal and I-20, and "Area Codes" with Nate Dogg.

During the spring of 2003, Ludacris returned to the music scene after a brief hiatus with a new single, "Act a Fool", from the 2 Fast 2 Furious soundtrack. At around the same time, he released the lead single from his album Chicken-n-Beer, called "P-Poppin" (short for "Pussy Poppin'"). Neither of his new singles were as well received by either the urban or pop audiences as his previous songs had been, and both music videos received only limited airplay. Chicken-N-Beer opened strongly, but without a popular single, the album fell quickly. Guest appearances include Playaz Circle, Chingy, Snoop Dogg, 8Ball & MJG, Lil' Flip, I-20, Lil Fate, and Shawnna.

In the fall of 2003, Ludacris rebounded with his next single, "Stand Up", which appeared on both Chicken-n-Beer as well as the soundtrack for the teen hip hop/dance movie, You Got Served. Produced by Kanye West, "Stand Up" went on to become one of Ludacris' biggest mainstream hits to date, hitting the top spot on the Billboard Hot 100 garnering heavy airplay on mainstream pop, rhythmic, and urban radio stations, as well as on MTV, MTV2, and BET. Ludacris was sued by a New Jersey group called I.O.F. who claimed that "Stand Up" used a hook from one of their songs, but in June 2006, a jury found that the song did not violate copyrights. "I hope the plaintiffs enjoyed their 15 minutes of fame," Ludacris said after the verdict.

The album's next single, "Splash Waterfalls", was released in early 2004. A huge pop hit (despite its steamy video and explicit, adult-oriented lyrical content and themes), it subsequently became a success at urban radio and BET, and is the only time he has produced two consecutive top 10 singles from a solo album,[citation needed] except for Release Therapy (an unedited version of the video could only be viewed on BET's Uncut program). It was Ludacris' most sexual video yet, an R&B remix that featured Raphael Saadiq and sampled Tony! Toni! Tone!'s "Whatever You Want". Ludacris received his first Grammy Award with Usher and Lil Jon for their hit single "Yeah!". Ludacris next released "Blow It Out", which was accompanied by a low-budget music video.

Chris Bridges took a more mature approach to his fourth album, The Red Light District. Sohail Khalid helped produce this album with various artists such as T.I., Lil Flip and Bun B. Ludacris openly boasted that he may be the only rapper able to keep the Def Jam label afloat on the opening track. Ludacris filmed and recorded the single "Get Back" in which he was featured as a muscle-bound hulk who was being annoyed by the media and warned critics to leave him alone. He first appeared on Saturday Night Live as a special guest performing with musical guest Sum 41 on a season 30 episode hosted by Paul Giamatti. He then recorded "Get Back" with Sum 41 to make a rock crossover single. The follow-up single was the Austin Powers-inspired "Number One Spot". It was produced by New York City's Hot 97 personality DJ Green Lantern. It used the Quincy Jones sample of "Soul Bossa Nova" and sped it up to the tempo of Ludacris' rap flow. Featured artists on the album include Nas, DJ Quik, DMX, Trick Daddy, Sleepy Brown, and Disturbing tha Peace newcomers Bobby Valentino, Dolla Boi, and Small World. The album debuted at number one on the Billboard charts.

In an issue of XXL, Ludacris was placed in the number nine spot for the most anticipated albums of 2006, for Release Therapy. The album Release Therapy was released on September 26, 2006. Ludacris formatted the CD to have two sides: a Release side and a Therapy side on a single CD. Guest appearances include Pharrell Williams, R. Kelly, Young Jeezy, Mary J. Blige, Field Mob, Bobby Valentino, Pimp C, C-Murder, and Beanie Sigel. The first single, "Money Maker", which features Pharrell Williams, was released to U.S. radio outlets on July 17, 2006. "Money Maker" reached number one on the BET program 106 & Park. It then went to become the rapper's second number one single after 6 years[citation needed]. His second single, "Grew Up a Screw Up", featuring Young Jeezy, dispels rumors that the two are or ever were in a dispute. His third single, "Runaway Love", soon peaked at number one on the U.S. Billboard Hot Rap Tracks and won Best Collaboration in the 2007 BET Awards. His album then reached number one on the Billboard 200 album charts with sales of 309,000 in its first week. With the release of this album, Ludacris marked a change in style in his career with his musical style. The new album itself features a departure of the lighthearted mood of his previous albums, and introduces a darker side. A change of hair accompanied this as he cut off his trademark braids for a more conventional "fade" cut. To promote the album, Ludacris returned to Saturday Night Live (as both host and musical guest) on November 18, 2006.

Kaci Lyn Battaglia (born October 3, 1987, Clearwater, Florida) also known as Kaci (pronounced /'ke?si/ KAY-see), is a singer, songwriter, dancer, actress, and professional kickboxing instructor.

She was born and raised in Clearwater, Florida, part of the Tampa Bay region. She is of U.K-American and German-American ancestry. Kaci's mother Donna remarried after a previous divorce to Kaci's step father Chuck Stanmore. Unfortunately the two split up in 2005. Battaglia began singing when she was three years old and soon began attending various performance camps around Florida. She is an only child.

At age 11, Kaci independently released "A Thousand Stars," an album that was produced by her mother, Donna. A portion of the proceeds from "A Thousand Stars," went to help a housing project for the less fortunate. Kaci began looking for a recording contract when she was eleven years old, due to the success of her independent album. She caught the eye of legendary record producer Joel Diamond after Kaci's mom called and asked Diamond to audition her daughter. Joel knew immediately even at 11 years old, Kaci was something special and put up his own money to record her. After being turned down by literally over 20 record labels with his recording (which he also co-wrote called "Paradise") it was Mike Curb who called Joel literally months after receiving the recording him and told Joel that he thought "Paradise" was a smash and wanted to sign Kaci to Curb Records. Her debut single "Paradise" was released in 2001 and hit #13 in England. Kaci's second single was a cover of David Cassidy's, "I Think I Love You," which by coincidence was also produced by Joel Diamond, who actually launched Katie Cassidy's entire career.. It was released around the same time of his own daughter, Katie Cassidy's cover of the same song. In 2003, Kaci teamed up with a Japanese photographer and released a photo book entitled, "Kaci: I'm A Singer." This photo book was filled with pictures of Kaci while in her hometown in Florida. The book was released exclusively in Japan, along with a re-release of her album, "Paradise," that included a bonus DVD with her music videos and clips from the making of the photo book. In 2005, Kaci recorded a song for the movie, "The Perfect Man" called "I Will Learn To Love Again." In 2007, Kaci released, "I Can't Help Myself," a track that was released to dance radio stations. In 2009 Kaci signed on with a major management agency called Big Management Ltd, and altered her artist name by adding her last name to her work, instead of only using her first name. Kaci is currently recording her next album, slated for a 2011 release with the first single being "Crazy Possessive" hitting the airwaves, has become a huge hit on Sirius XM Radio, beating both Black Eyed Peas and Eminem. The single "Crazy Possessive" was released via iTunes and Amazon.com on May 26, 2009. Kaci's relationship status is currently unknown. Also just as a note, "Paradise" which was co-written by Joel Diamond was also originally produced by Joel for actress Phoebe Cates and hit #1 in Italy and became an Italian "standard" over there.
