Stacy Keibler flashes thong in wardrobe malfunction at Grand Prix

stacy-keibler-flashes-thong-wardrobe-malfunction-grand-prix.jpg Stacy Keibler is usually one of the most stunning women when there is a red carpet around, but at the 2013 Grand Prix it looks like she forgot one key step before she stepped out -- zipping up her outfit.

At the Formula One F1 Grand Prix in Monte Carlo, Monaco, over the weekend, George Clooney's main squeeze was sporting an adorable belted coral jumper, but the zipper on the side revealed a pink thong underneath. Oops.

The former "Dancing With the Stars" contestant looks unconcerned, which means she probably didn't know the zipper was down. We would imagine that at some point, somebody let her know.

And hey, at least we don't have remind Keibler to wear underwear in the first place.
