Did K-Fed Cheat with a Porn Star?

Did K-Fed really cheat on Britney? We've heard this theory before, and now Star is reporting that this is the reason why Brit decided to leave Kevin. Apparently he was having an affair with an exotic dancer and former porn star who he met in Vegas. We all know how much Kevin likes to spend time in Vegas without Britney... could this really be the reason? Here's more:

Add this to the reasons that Britney Spears had to dump her hubby: Kevin Federline reportedly was having an affair with a former porn star a full month before Spears filed for divorce in November.

Federline met Kendra Jade, an “exotic dancer” and former porn star, in Las Vegas in December 2005 while his wife was visiting her family in Kentwood, Louisiana, according to Star magazine, and the two stayed in touch.

“Kev and Kendra had sex at their friends’ apartment multiple times, starting in early October,” a source told the tab. “Their friend would phone Kendra and a few other girls to come hang out, and it would always end up with Kevin and Kendra heading off to the spare bedroom!”

Now that K-Fed is a single guy, will he and Jade become a couple? Not likely, says the source, explaining, “They’re just friends who have sex.”

When contacted for comment by Star, Jade said only, “I’m in a committed relationship.”
