Actor Robert Downey Jr. has stunned Hollywood with a wild accusation - every movie's leading man "goes to bed" with his female co-star.

The Zodiac star openly admits he's indulged his sexual desires on movie sets in the past, and insists such intimate activity between co-stars is inevitable - because they spend so much together in such a close environment.

He says, "I remember certain colleagues having a lot of fun on the set with me. Every second star goers to bed with his co-star because they spend so much time together. But I'm not going to start reeling off the names."
