Kevin Federline is Britney Spears' ex-husband and the father of her children. His high profile marriage launched him into the public eye, all of whom were watching when he released his first album. Prior to his record release, Federline's contribution to the music industry was as a dancer. Before meeting Spears, Federline, aka K-Fed, worked as a pizza delivery boy and a dancer, performing in the live shows of pop acts such as Justin Timberlake, Pink, and Michael Jackson, and danced in the 2004 movie You Got Served. Shortly after the wedding, Federline began recording songs in the couple's home studio, and some tracks soon leaked onto the Internet. The first, "Y'All Ain't Ready," arrived late in 2005 and was produced by Hollertronix's Disco D, but the song was lambasted for Federline's lyrics, which described his rapping style as "straight 2008" and called paparazzi photographers "pavarottis." His next attempt, "PopoZao" (Brazilian slang for "big butt"), was released on New Year's Day 2006. Its silliness, which was emphasized by a video of Federline grooving along to the track in the studio, and its equally poor critical reception made it a pop culture phenomenon and catch-phrase for the better part of that year. K-Fed's first official single became "Lose Control," which he debuted on the Teen Choice Awards show in late summer 2006.
