Robert Downey Jr. is one lucky dad!
He's got a super awesome movie coming out, PLUS his baby is one of the most adorable things we've ever seen.
Ch-ch-check out the pic (above)! ADORABLE, right?? The Down-man shared the (above) baby picture with his wife Susan during his appearance on The Late Night Show With Jay Leno - and of course, it took some coaxing!
The audience pleaded and begged, but FINALLY, Mr. Iron Man himself gave in and introduced the world to little Exton Elias.
We can tell he's going to be an Avenger one day, just like his poppa!
