Stacy Keibler suffers wardrobe malfunction at Monaco Grand Prix

Photographers spotted Stacy Keibler in Monaco for the Grand Prix race wearing a bright red romper. But unfortunately for the 33-year-old actress and model, cameras also caught her tiny pink thong peeking through the side of her outfit where a zipper had come undone.

(US Weekly has a close-up photo of the wardrobe malfunction.)

While watching the race later, Keibler covered the romper with a dark jacket. "So close to all the action!" she tweeted.

She also spent her time on the French Riviera drinking with royalty.

"Heading 2 the palace for cocktails w Prince Albert & Princess Charlene," she wrote Monday.
