Robert Downey Jr and his wife are the proud parents of a baby boy.

The Iron Man star and Susan Levin, his wife of nearly seven years, welcomed 7lb 5oz Exton Elias Downey in Los Angeles on Tuesday, reports People.

A friend said: "Everyone is healthy and they couldn't be happier."

Robert, 46, and producer Susan, 38, already knew they were expecting a baby boy but had not revealed his name.

Robert - who is set to star in a third instalment of the Iron Man series - already has an 18-year-old son, Indio, from his marriage to Deborah Falconer.
