Kevin Earl Federline (born 21 March 1978), sometimes known as K-Fed, is an American dancer and star of the reality television show Britney and Kevin: Chaotic. On the night of September 18, 2004, a mere two months after his son was born to Shar Jackson, he married Britney Spears in a non-denominational surprise ceremony at a private home in Studio City, California before 20-30 guests. Britney reportedly had to pay for her five carat (1 g) engagement ring, and initially refused to have Federline sign a prenuptial agreement, although later he did sign one. Federline has two small children with actress Shar Jackson. He began to date Britney Spears during Shar's second pregnancy. On April 12th, 2005, Britney Spears announced through her website that she was expecting her first child with Kevin, due in Autumn.

Before meeting Britney, Federline worked as a back-up dancer for Spears' ex-boyfriend, Justin Timberlake.

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 the summer of 2005 media reports indicated Federline's wife, pop star Britney Spears, was pressuring him to seek employment.
