"Real Housewives of New York" star Aviva Drescher is invading the Miami housewives' turf -- and showing off her impressive body while doing it!

The 42-year-old mother-of-four hit the surf in South Beach on Thursday, where she flaunted her fit physique in a maroon two-piece bikini.

Drescher, who lost her left leg in a farming accident when she was six, was seen enjoying a family vacation with three of her children: Veronica, Hudson and Harrison.

Aviva was one of the latest additions to the Bravo show last season, along with Carole Radziwill and Heather Thompson. So far, it looks like Drescher will be returning for Season Six ... no word on the others.
