Talk about an oops moment: George Clooney's prettier half, Stacy Keibler, suffered a wardrobe malfunction this weekend at Monaco Grand Prix when the zipper on her romper came undone, according to the Daily Mail.

Keibler, the 33-year old girlfriend of actor, George Clooney, is known for her uncanny ability to make just about any ensemble look good. But even Keibler proved that even she is not immune to wardrobe malfunctions, according to the DailyMail.

Stacy clearly hadn't noticed that her outfit had come undone, showing off a pink g-string underneath and a significant dash of thigh.

From a front-on angle, everything seemed just fine - Stacy was nothing less than the flawless bombshell she's known to be.

It was only when the blonde starlet varied her pose by turning to the side that the wardrobe malfunction became evident.

Inches of the romper's zipper had slid all the way down, and judging by the beaming smile on Stacy's face, she had no idea.

Surely something the smiling model and actress would have rather kept hidden beneath the red ensemble, hopefully somebody was kind enough to tell her of the mishap.

And yes, despite rumors Keibler and Clooney had broken up, partly fueled by an accidental slip of the tongue by Clooney's pal Mark Wahlberg last week, they are still together, apparently.

Back in March, rumors were swirling that Keibler and her A-List boyfriend were splitting, citing the couple's noticeable age difference as cause. Days later though, the former wrestler was spotted visiting her hunky man Clooney in Berlin, where he was filming "The Monuments Men."

Oh, those rich and famous couples. Always under the bright lights.
