The Real Housewives of New York Season 5 introduced us to Heather Thomson. Whatever else you think of the newbie housewife, it is quite clear that she's a shrewd businesswoman who has built quite the shapewear empire with Yummie Tummie. Now, Heather is taking on the shapewear kings, Spanx — in court!

As Today reports, last week Heather filed a suit with the U.S. district court in NYC, claiming that Spanx's slimming tank tops copy her patented Yunnie Tummy designs. She's suing for sales injunctions against the allegedly copied designs — meaning Spanx would have to stop selling their versions of the tanks —  as well as unspecified damages.

Heather's Spanx saga started back in January, when her company sent Spanx a cease-and-desist letter, which Spanx responded to in March "by filing documents in federal court in Atlanta requesting a judicial declaration that Spanx was not infringing on Yummie Tummie designs and asking Thomson’s company to pay its legal fees."

Who will come out on top of this shapewear battle? It goes without saying that we're hoping Heather wins her case. We'll keep you updated!
