Justin Timberlake is a smooth operator in more ways than one.

According to celebrity bodyguard Lee Weaver, Timberlake once defused a beef between his then-girlfriend Cameron Diaz and troubled starlet Lindsay Lohan.

Celebrities Who Have Admitted To Smoking Pot

RadarOnline.com obtained an exclusive copy of Weaver’s new book, Memoirs of a Celebrity Bodyguard, in which he details a night out on duty with Lohan at a Hollywood club where they ran into Diaz and Timberlake.

“They sat right next to us in another booth,” Weaver writes. “Right after that I heard one of Lindsay’s girlfriend say, ‘There is that b**ch! Go kick her a** right now.’”

A former bodyguard for Britney Spears is charging that she hit her children, had sex in front of them and made them eat until they vomited.

The charges are contained in a shocking lawsuit that Fernando Flores, the former guard, plans to file against Spears on Wednesday. RadarOnline.com has seen a copy of the suit.

Flores also contends that Britney sexually harassed him, creating situations where Flores saw her naked or partially exposed.

At a hotel in California, “Plaintiff perceived, during security checks of the perimeter, Defendant loudly having sexual relations while her two children were in the suite with her,” Flores is set to charge in the suit.
