Teresa Guidice and Joe Guidice Cheating RUMORS: 'RHONJ' Starlet BASHES Claims that Husband is Sleeping with Younger Look-alike Nanny Nicole Cemelli

A recent cover issue of Life & Style blares the headline, "Joe [Guidice] Cheat with the NANNY!" Apparently, "Real Housewives of New Jersey" starlet Teresa Guidice's husband has been sleeping around with the attractive young woman who helps take care of the couple's four daughters. The tabloid claims that Teresa puts up with the infidelity because she comes from a traditional Italian family and they doesn't believe in divorce. The Bravo reality starlet recently took to her own blog to debunk the shady cheating rumors, insisting that they're all lies. Read on for more deets!

Life & Style claims that the Guidice's 13-year marriage may be coming to an end because of 20-something-year-old Nicole Cemelli, the attractive young woman hired to watch the couple's four children. Apparently, Cemelli "bears a striking resemblance to Teresa" when she was younger. The tabloid explains - "Rumors of Joe's shameful philandering have run rampant since the show premiered in 2009... [but] Teresa comes from a very religious Italian family that doesn't believe in divorce - that's why she's put up with so much."  

Now, Teresa's fighting back. Here's the heated blog post she posted on Wednesday, June 4:

"I hear you're trying to get to the bottom of the 'mystery girl' Joe had drinks with in April? Here's a simple idea: show me or Joe the picture and ask us. We could have easily told you it was one of our dear friends and a former employee of both of us that Joe was meeting to talk business. We've known her and her family since she was in high school. No secret. No mystery.

I'm also in business meetings and lunches and dinners with people of the opposite sex. Should I send you their photo before we go out so you're clear on that too? Or will you continue to make up stories about everyone we meet? I have a book signing tonight in Boston--at Brookline Booksmith, 279 Harvard Street. Be sure to come over and photograph me with the 300 or so hot guys I'm sure will be there. I'm in a relationship with ALL of them! I'm just that busy.

Joe and I are on TV, so I get it that our lives are open for everyone and their mother to criticize. What's unfair and completely disgusting is that you would drag every person we ever speak to into your fake stories. It's not acceptable to falsely portray our friends, family, business associates, fans, and even acquaintances this way. 

The poor girl in your photo is freaking out now, and rightfully so, because she's getting harassing calls at her work, being stalked on the Internet, and even followed. How is this even remotely legal? Oh yeah, it's not. 

You know we have four daughters that are personally hurt every time you print these lies, but that doesn't seem to faze you at all. Maybe being sued for defamation finally will."

So what do Mstars readers believe... is Joe really cheating?
