Frankel Stays True to her Brand

Best way to sell a product called Skinny Girl?  Wear a bikini.

Bethenny Frankel is currently vacationing in Miami and showing off her tiny physique in an array of itsy bitsy bikinis.  She brought along her daughter, Bryn, as well and the two were spotted having some mother-daughter time by the hotel pool.

Although becoming a true skinny girl takes more than just sitting around drinking delicious margaritas, Bethenny sure knows how to make a darned good one.  And at only 100 calories a glass, our real concern is why we aren't drinking one right now.
