Robert Downey Jr. Flashes Underwear At ‘Sherlock Holmes’ Rome Premiere [PHOTOS]

I’ve heard that men tuck their undershirts in to their underwear, but I’ve never heard of men tucking their shirts in to their underwear. Well, that’s exactly what Robert Downey Jr. did while dressing for the Rome premiere of Sherlock Holmes: A Game of Shadows.

While waving to the crowd on the red carpet at last night’s (December 11) premiere for the film, Robert exposed his red Calvin Klein banded underwear. Oops.

The father-to-be recently revealed that he was embarrassed to cross dress for a particular scene in the film as he thought that his wife was watching him.

In one particular disguise scene in his upcoming flick Sherlock Holmes: A Game of Shadows the actor was dolled up to look like a lady, while his wife Susan (producer) sat behind-the-lens and attempted to work.

Fox News quoted him as saying, “I keep thinking, is my wife sitting behind the monitor and watching me cross dress on purpose?”
