Allegedly, Justin hasn't always been faithful to Jessica, his on-and-off girlfriend of four and a half years. According to an Us Weekly source, "Everybody knows Justin has a wandering eye, and Jess knows too." But the supposed insider insists Jess won't put up with JT's womanizing ways now that he put a ring on it. "There is no way Jessica will deal with his straying eye now that they're engaged," claims the source. "You are going to see some changes from Justin."
During his breaks with Biel, Justin reportedly hooked up with comedienne Olivia Munn and actress Olivia Wilde. "Justin really loves Jessica, but he just can't stay monogamous," the insider spills. "His brain and his penis operate separately, and the brain proposed to her. He thinks it is what he wants, but he has two sides -- and the other will pop back up. He has a big sexual appetite."
Apparently Justin's partying pals are no help. "He's surrounded by a bunch of people who would do anything to stay in his good graces. They're so afraid of being booted out of the circle, they'll hide all his secrets," another source reported. Biel is apparently very aware of this fact, and has made it her mission to keep her man on close watch to prevent any slip-ups. "She knows she's going to have to limit the amount of time that Justin spends with his clubbing friends." Still, friends apparently worry this will only make Justin "more strategic about his affairs."
