Kevin Earl Federline (born 21 March 1978 in Fresno County, California, USA), who sometimes refers to himself as "K-Fed," is an American dancer and aspiring rapper, husband of pop singer Britney Spears, and co-star of the reality television show Britney and Kevin: Chaotic, which consisted of home videos from the couple.
The relationship between Spears and Federline, chronicled in Chaotic, began with their meeting at a Hollywood club called Joseph's and then setting off on her European tour, The Onyx Hotel Tour. Spears proposed to Federline on the plane ride back from the tour. She reportedly had to buy her own engagement ring. On the night of September 18, 2004, less than two months after his second child was born to actress Shar Jackson, he married Spears in a non-denominational surprise ceremony at a private home in Studio City, California. Spears initially refused to have Federline sign a prenuptial agreement, although later he did sign one at the request of Spears' mother. Federline has two children with Jackson: daughter Kori (b. 31 July 2002) and son Kaleb (b. 20 July 2004).
Before meeting Spears, Federline worked as a back-up dancer for Spears' ex-boyfriend, Justin Timberlake. He and Spears began dating while Jackson was still pregnant with Kaleb. On April 12th, 2005, Spears announced through her website that she was expecting her first child with Federline. A son, Sean Preston Federline, was born on September 14, 2005.
Federline has been the subject of much media ridicule. The popular website Fark insists on referring to him as Cletus, a reference to Cletus and Brandine Spuckler, the "slack-jawed yokels" from The Simpsons, and sometimes to Spears as Brandine, especially when stories (from "sources") of the couple's allegedly malodorous lack of hygiene appeared in an edition of the tabloid The Globe. In an episode of Family Guy, a fantasy sequence features Federline asking a magic mirror how he can "look like a douchebag today." The mirror tells him to not shave, shower, or change clothing, and to "walk around with an undeserved sense of accomplishment." Saturday Night Live featured a mock TV commercial for "Federline Briefs" underwear, with Kevin played by guest host Ashton Kutcher.
Federline's first studio album is due out in summer 2006. A minute-long clip from the track "Y'All Ain't Ready" circulated on the Internet in November 2005 to dreadful reviews and much ridicule. The album is rumored to be released sometime in 2006, even as early as February. [1]
