Reality star turned entrepreneur Bethenny Frankel is an experienced roller skater, having closed out a season of ABC's "Skating with the Stars" as the runner-up. However, a recent gaffe of hers proves that even seasoned skaters fumble now and again.

Frankel laced up her skates for the opening of Flipper's Roller Boogie Palace, hosted by Usher. In a video obtained by TMZ, the former "Real Housewives of New York City" star touches up her lip gloss and confidently busts a move on wheels before landing squarely on her backside.

Fortunately, a friend sprang into action and helped Frankel up. The Twitterverse chimed in to comment on Frankel's fall: "Happens to everyone," one user said matter-of-factly. Meanwhile, another tweeted, "she'll be pissed about this. she was showing off & went splat."
