The proud papa opened up to David Letterman about his three kids. "I have three; a 21-year-old, Indio, a 3-year-old, Exton, and now Avri, a little over 5 months. I thought I'd show the first picture on planet earth here with you, kind sir."
Letterman loved it, saying, "That's sweet!” Downey replied, "The yellow bonnet helps! You gotta love a yellow bonnet."
The talk show host went on to ask the “Age of Ultron” star what the dynamic was between Exton and Avri. Downey grinned, "Well, she's female.” He said there’s no rivalry yet between the two, but “It's natural for Exton to want to bite her once in a while. It can start off as a little pet, and then it turns into a little nibble.”
He also revealed how things run in the Downey household, adding, “She'll be running stuff at some point.”
