Robert Downey Jr. hung out poolside in Miami with his family yesterday. He held onto baby Exton, who was born to Robert and his wife, Susan, in February, and went shirtless in the sun. Robert was sporting an ankle brace after injuring himself on the set of Iron Man 3 in August. Production was slightly delayed due to the trauma, though Robert has since returned to work and was spotted filming in Florida today. The third installment of the franchise doesn't hit theaters until next May, but you can see RDJ in his action role now, since The Avengers was released on DVD last week.
