Robert Downey Jr. Flashes Underwear On 'Sherlock Holmes' Red Carpet (PHOTO)

Robert Downey Jr. may have been wise to ask someone 'how do I look?' before stepping out at Sunday evening's red carpet premiere of "Sherlock Holmes: A Game of Shadows" in Italy. The actor gave a thumbs up to eager photographers who were no doubt whispering about Downey's wardrobe malfunction rather than his stellar ensemble.

Peeking out from his trousers were Downey's red knickers -- the Calvin Klein logo was clearly visible. This is the second time Downey has walked the red carpet for his role as the mischievous investigator, the first installment of the "Sherlock Holmes" series was released in 2009, but the first time he's done so giving us such an eyeful.

"Sherlock Holmes: A Game of Shadows" hits theaters Dec. 16.
