Real Housewives of New Jersey star Joe Giudice left behind his wife Teresa to have dinner with a mystery woman on Dec. 27, according to an eyewitness.

Joe and the unidentified woman went to La Havana 59 in Moonachie, N.J., not far from the home he shared with Teresa and their daughters. They were spotted walking into the restaurant together at 7:30 p.m. and left after 9, Radar Online reported.

"Joe sat across from the woman, who was very attractive, probably in her 30s, had long brown hair and was dressed very nicely in knee-high stiletto boots and she was carrying what looked like an expensive purse," an eyewitness told the website. "After people started noticing him and taking pictures he actually moved to sit next to her so that his back was to most of the restaurant."

The source also ruled out the possibility of them having a business meeting, saying, "They didn't have any papers on the table, they didn't have a briefcase or anything and they were just laughing with each other the whole time."

The insider added that Joe leaned in closer to the woman several times during their conversation.

This isn't the first time Joe was seen having dinner with a woman who is not Teresa -- it's the third. He had lunch with a brunette woman in November 2013 and also with a female at TGIFriday's in 2011.

Teresa and Joe's fraud trial will not be shown in season 6 of The Real Housewives of New Jersey, which is scheduled to premiere on Bravo in early 2014. The cast members began filming the first week of December.
