Britney Spears and Kevin Federline [AFP]

Kevin Federline's debut album will be released soon but without featuring the song about women's posteriors called 'PopoZao', in favor of a duet with wife Britney Spears titled 'Crazy'.

It was in January this year that K-fed unleashed his rapping talents with ‘PopoZao,’ with Billboard magazine calling it "a monument to mediocrity."

According to inside reports, one of the rappers who had claimed that he'd written some of the rhymes for K-Fed disassociated himself from the song after its release.

"I didn't have nothing to do with that dog," TMZ.com quoted him, as saying.

The first 500 fans that pre-order Federline's debut album titled ‘Playing With Fire’ via his online store will apparently receive an autographed photo. All pre-orders will then be entered into a contest to attend a record release party in Los Angeles hosted by Spears. (ANI)
