Teresa Giudice is still a married woman, but In Touch has learned that the Real Housewives of New Jersey star, 45, wasn’t acting like it while vacationing at Moon Palace Cancun in Mexico over the holidays.

“Teresa’s winter getaway seemed to be all about letting her hair down,” an eyewitness explains, adding that Teresa’s hubby, Joe, 45 — who is in prison on fraud charges — didn’t seem to be on her mind.

“Teresa was flirting with guys. She wore a series of eye-popping bikinis and no wedding ring. She got a lot of attention from men,” an eyewitness tells In Touch.
