Life& Style Magazine also reports that Spears caught the failed rapper with another woman. "Britney walked into their suite, and there was a friend of Kevin's and a blonde walking around in her bra and panties," says a Spears business insider. "Kev acted like it was no big deal. He told Brit he needed a little distraction to get ready for his record-release party the next day."

Rather than launch into a fight, Britney called her management team and had them kick Kevin out of the hotel. "Kevin totally ignored the fidelity part of marriage, and he didn't care if he broke Britney's heart," claims the insider.

Catching Kevin was the last straw, but Brit may have been looking for an excuse to dump him. She'd heard rumors of his cheating in the past and had seen photos of him with other women. And they had a huge fight on Halloween after she saw him flirting up a storm at LA club Xenii.

But even though Britney has finally put an end to their rocky marriage, her troubles aren't quite behind her yet.

Now , reports have again surfaced of a steamy sex tape involving Britney and Kevin, only two days after Britney filed for divorce. The tape could make up to $200 million if it sees the light of day, dwarfing the profits from Paris Hilton's sex-tape sales. However, many think that K-Fed may be behind the tape's conveniently timed arrival. He signed and iron-clad pre-nup at Britney's insistence before they wed, and only stands to receive $300,000 alimony for two years of Britney's estimated $100 million net worth. K-Fed has tried other slimy moves to get more money, such as filing for sole custody of the kids against Britney's motion, and flinging accusations that she only used him to father the two children she always wanted to finagle a better settlement. However, with at least four confirmed sightings of Kevin with other women, including former adult movie star Kendra Jade, Britney is ready to be rid of this two-timing loser, and reportedly told her lawyer that she would pay up to $15 million just to get him to go away! After regaining her killer body, and setting up recording with A-list producers such as Pharrell Williams and Scott Scorch she's ready to get her life and career back on track without her now Fed-Ex.
