Robert Downey Jr.'s youngest children fighting for 'dominance'
Robert Downey Jr.'s youngest children are fighting for "dominance".
The 'Avengers: Age of Ultron' star has revealed three-year-old son Exton and five-month-old daughter Avri - who he has with wife Susan Downey - have already got a little rivalry going on between them.
He joked: "I mean it's natural for Exton to want to bite her once in a while. It can start off as a little peck and then it turns into a nibble.
"I think it's just establishing dominance but she'll be running stuff at some point."
During his appearance on 'The Late Show with David Letterman', Robert, who also has 21-year-old son Indio from his previous marriage to Deborah Falconer, revealed the "first picture on planet Earth" of his little girl.
Introducing the little one, he said: "I have three [children] a 21-year-old, Indio, a 3-year-old, Exton, and now Avri is a little over five months.
"I thought I'd show the first picture on planet earth here with you, kind sir."
David replied to say: "That's sweet. She's beautiful."
The picture showed little Avri, with her bright blue eyes, wearing a tiny orange bonnet hat.
