Ain't nothin' but a G-string for Stacy Keibler! George Clooney's actress/model girlfriend made a solo appearance in Monaco on Sunday, May 27 for its annual, super-duper glitzy Grand Prix. Happily posing for a photographer at Amber Lounge, a nightclub in the posh French Riviera city-state, Keibler, 33, looked sexy and carefree as ever in a short red, belted romper that showcased her slim toned arms and legs — and an embarrassing glimpse of pink G-string underwear underneath!

With the former pro wrestler grinning, seemingly oblivious, cameras caught a busted zipper on the right side of the romper at the waist-line, revealing her pink underwear beneath.

Keibler reported from her Twitter account that she was soaking up the glitz and glamour of Monaco and the Grand Prix over thew weekend. "Heading 2 the palace for cocktails w Prince Albert & Princess Charlene," she wrote on Monday — noting the day before that she was "so close to all the action" during the Grand Prix race itself.

Her love Clooney, 52, has been shooting The Monuments Men elsewhere in Europe.
