Our favorite superhero/funnyman is celebrating his 52nd birthday! The one and only Robert Downey Jr., is ringing in his special day today and we're honoring the big event with 9 of the Iron Man star's most humorous social media moments to date.
When Downey isn't dressed up as the iconic superhero, a role he'll be reprising next year in Avengers: Infinity War, he's giving back to his community and fans—like the time when he presented a 3D-printed, real-life bionic arm to a 8-year-old boy with a partially developed limb—and of course, being a father. The star shares 23-year-old son Indio with ex Deborah Falconer, and he and wife Susan Downey are also proud parents to 5-year-old son Exton and 2-year-old daughter Avri.
