Rober Downey Jr. looks SO HAPPY!
The star's wife stole the show at the Sherlock Holmes 2 red carpet!
Look at him! RDJ's goofy grin says can only be caused by the thrill of fatherhood. He so cute!
The beaming father recently announced that his wife Susan is carrying his second son.
We seriously hope he looks as cute as Robert did when he was a kid.
