Britney Spears' husband, Kevin Federline, announced on Ryan Seacrest's Los Angeles radio show Thursday that he's putting out a hip-hop album. Federline said his first single will be the song, "PopoZao," Brazilian slang for big butt, TMZ.com reported. The dancer-turned-rapper spent much of the interview denying tabloid reports of trouble in paradise. He said Spears has not kicked him out of their home or taken away his Ferrari and described life with his pop star wife and infant son as one big happy family. As for the album, the star of the film "You Got Served," said Spears sings on a few of the tracks. A release date for the album is pending, he said.
