Did Britney Spears Cheat On Kevin Federline?

Star Magazine is reporting that Britney Spears hooked up with J.R. Rotem BEFORE she officially filed her divorce papers. Does that mean that Kevin Federline stands to make more money from the divorce if it's true? Is it true? We only saw them together once. I think it was just a random hook up. Since then, JR has been spotted with Paris, Hayden and Bai. I say JR has one heck of a PR team working on making him the next greatest thing since sliced bread. But who knows!?

On December 10, J.R. Rotem, 31-year old South Africa-born music producer, was spotted smoothing with a cute blonde at L.A.'s 3rd spot restaurant around 11 p.m., and the mysterious blonde was none other than Britney Spears, who he's currently working with for her comeback album. On December 12, Star spoke exclusively with J.R. Rotem, head over heals for Brit raving, "Everything she does is amazing." The two may not be an official couple, but J.R. did say the "girl he is dating".
A source tells Star that the two were hooking up before Brit filed for her divorce papers, and another source reveals, "there were rumors circulating for a couple of months regarding Britney and J.R... .they shared definite chemistry." This source did confirm that Brit and J.R. waited before pursing anything until after Kevin was out of the picture. J.R and Brit haven't been spotted together recently; J.R.'s homebody style doesn't really fit with Brit's crazy partying. Brit's not the first party girl for J.R.; he also had a fling with Paris Hilton while working on her debut CD. A Star insider reveals "it was nothing serious, just a few hookups... I bet a million dollars that J.R. tied to keep that a secret from Britney... (she) would probably flip out if she knew that he'd romanced Paris first."
