Bethenny Frankel Teases Illness, Flogs Booze

Bethenny Frankel invited her “Real Housewives of New York City” costars out for drinks last night, but not just any drink — her new Skinnygirl Cocktails Watermelon Lime Margarita.

Oh, and she also teased the scary health problem that will be a plotline on the upcoming season eight of RHONYC, but refused to spoil the big reveal by actually naming the problem.

LuAnn de Lesseps, Sonja Morgan, Bethenny, Ramona Singer, Carole Radziwill and Dorinda Medley all made it to Bethenny Frankel's Mexican Fiesta, to sample the Watermelon Lime Margarita.

Bethenny’s fiesta party featured the new cocktail, which will be available this summer, displayed in a special bottle designed by pop artist Romeo Britto just for the party. So don’t get attached — the bottle will not be for sale!

"I'm facing a women's health issue that many women can relate to," Bethenny, 45, told People magazine. "I'm dealing with it head on and viewers will understand how I personally deal with matters such as this. I hope women can relate, learn and support each other in life moments like this."
