Britney Spears, newly single, may have a thing for girl-on-girl action! In an upcoming issue by In Touch Weekly Magazine, the publication claims Britney was having lesbian sex during her marriage to K-Fed! 

The mag quotes K-Fed’s pal, rap music producer Omar "Iceman" Sharif, as saying: "Britney was into threesomes and girls."

The producer also claims Brit would invite females over to her and K-Fed’s house to "party".

Maybe Britney’s lesbian affairs had something to do with Isaac dumping her? Apparently Isaac couldn’t handle the pop princess. According to him, Brit was "a bit much", so he called her and ended the relationship.

Isaac dumped the ‘Toxic’ singer on Sunday night while he was far, far away from her - I mean he was in L.A. and she was in N.Y., according to OK! Magazine.

TMZ scoops: ‘According to a friend, Isaac has been "looking to get out" for some time, because it was "a bit much for him … it was too much of a whirlwind." And now, speculates the OK!, Isaac will resume his utterly anonymous existence, "riding his dirt bike" and focusing on "his career." As for Britney, send any and all spare underwear stat.’
