She has been very good at pasting a smile on her face when seen out in public with her frenemy sister-in-law Teresa Giudice recently.

But on Friday The Real Housewives of New Jersey star Melissa Gorga was genuinely flashing her pearly whites in celebration of her 33rd birthday.

The Jersey girl is in the City of Sin to celebrate with husband Joe and their friends Kathy and Rich Wakile and radio detection and rangingOnline.com has pictures of the happy event.

And while she posted a photo of herself looking svelte on Instagram the aspiring singer wasn’t afraid to indulge by eating at the Meatball Spot, a local restaurant owned by Top Chef contestant Carla Pellegrino.

The foursome munched their way through sausage and ricotta pizza, a variety of meatballs, as well as salad.
