Robert Downey Jr & Wife Susan Pictures The Avengers Premiere

Robert Downey Jr. stuck close by his wife Susan Downey at this evening's world premiere of The Avengers at El Capitan Theatre in LA. It was Susan's first red carpet outing since giving birth to their new son Exton in early February. The Avengers boasts quite the star-studded cast, but one person missing was the leading lady to RDJ's Iron Man, Pepper Potts. Gwyneth Paltrow missed out on this evening's event, though she and RDJ did get to team up to present at the 2012 Oscars. There are still a handful of weeks for The Avengers cast to promote their movie together before its May 4 debut, and in case you missed it, watch our interviews with Scarlett Johansson, Chris Hemsworth, Jeremy Renner, and more!
