Picture this: You're walking around outside when you randomly see actor Robert Downey, Jr. standing around with a black suitcase. You say to yourself, "I'll pretend to take a selfie so I can really get a photo of him." Unbeknownst to you, RDJ's aware of your plan — very well aware of your plan.
Such is the life for this gal who happened upon Iron Man. When RDJ realized she was secretly trying to snap a pic, he threw up his best Breakfast Club fist pump and the rest is history.
The 49-year-old was such a big fan of the moment that he decided to post the image on his Facebook account, with the caption: "You're never too old, busy, or famous for a good photobomb."
And that's exactly why he puts his fellow 13 star photobombers to shame. See their pics below!
