How Much Did Justin Timberlake Really Cheat on Jessica Biel?

A lot! This may surprise you considering he's such a shy quiet young man who's never been known to have any problems with keeping it in his pants, but apparently Justin Timberlake was not only banging half the young actresses and singers in Hollywood while he was still dating Jessica Biel, he was also hooking up with random waitresses and bar skanks.

At least that's the case according to US Weekly which has compiled a list of JT's alleged infidelities. Think of it as the Cliff Notes version of Justin's man-whorin'. Some highlights:

-Winter 2007: JT hooks up with a girl he met at a bar and had only spoken to for 15 minutes.

-JT tried to get with Rihanna circa Fall 2008, but she "would not go there."

-Ciara also wasn't into it.

-Kate Hudson and JT might have hooked up in December 2009 - just before Kate and Alex Rodriguez split.

-March 2010: he was cozying up to a "handsy waitress" in Las Vegas.

-Fall 2010: Olivia Munn. They met in September and immediately began an affair. A source says they had "amazing sex." A source says Timberlake wanted to continue the affair, but Olivia "didn't want to be the other woman."

There are many, many more items on the list and, yes, it's unlikely that everything here is true, but I'd say it's equally likely that it's all made up. The occasional drunk accident is one thing, but whenever I hear about rampant, calculated cheating like this, all I can think is, "Dude, why didn't you just grow a pair and break-up with her?"
