This will be the first child for Susan, 37, while Robert, 46, is father to 18-year-old Indio, his son with his ex-wife (Deborah Falconer).

Downey’s rep told PEOPLE “Robert and Susan could not be more excited over this news…They can’t wait to welcome this new baby into their wonderful family.”

In an earlier interview, Downey Jr spoke with pride about his 18 year-old-son: ‘My son is gifted and artistic and has a great sense of humor, yet he’s a very contemplative guy. That’s good. I don’t want him to be in a hurry to find out who he is.”
