It's Worse Than Teresa Knows! Joe Giudice Has 'At Least A Dozen' Secret Mistresses, Friend Claims

How much more can Teresa Giudice take? Forced to watch explosive reports of Joe Giudice's affair with Jamie Jackson play out from behind bars, the Real Housewives of New Jersey star is facing the most brutal assault on her marriage yet. And RadarOnline.com can now reveal that it's about to get worse — because an insider tells RadarOnline.com Jackson is only one of Joe's many mistresses!

"Jamie is not the only girl out there. Joe probably has a dozen mistresses out there, if not more!" a source close to Joe, 42, tells RadarOnline.com.

Though rumors of Joe's infidelity have been around for years, the couple have put on a united front in recent months as they faced their looming prison sentences. But, according to the source, their united front was just an act.

"Joe is always going out and is rarely home. He loves to go out and drink and party, and he's always hanging around with different women," said the source. "Joe has never changed his ways, and Joe will never change—ever."
