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)
