Never one to back down from a challenge thrown down by a man, former Real Housewife of New York Bethenny Frankel stepped up to the plate when Anderson Cooper challenged her to a push-up contest this week on his show.

Unfortunately, in pink platformed heels and a sundress, B wasn't quite dressed for the occasion. When she jumped down to begin her reps, the back of her dress flew up over her bum, exposing her pink-panty clad (and perfectly sculpted, of course) derriere to the audience.

The Bethenny Ever After star handled the candid moment with humor and charm, natch, first giving Anderson a "whoopsies" face, and then asking the audience, "So how'd it look?"

Said audience, of course, found it hilarious (who needs free cars, Oprah? Give us a little H'Wife tush now and again and we'd be happy), and encouragingly cheered her onto the contest.

(Spoiler alert: she and Anderson tied around 13 push-ups each.)

Bethenny's episode of Anderson Cooper airs today at 4:00pm ET. Sadly, for those watching at home, the wardrobe malfunction gets blurred out in the episode. Whomp whomp.
