"Robert and Susan could not be more excited over this news," his rep tells PEOPLE. "They can't wait to welcome this new baby into their wonderful family."
"I think we should probably try to have a girl because I don't want another male entity to have to compete," he said. "I don't want Indio to feel there's another boy in my life. But I don't know what we'd have to do [to have a girl]. Do we have to put it in a spoon and hang it upside-down?"Cute. Hopefully he'll get his girl.
The couple has been married for 6 years.
