The couple, together since 2004 and married since 2010, have three children (Noah, 4, Bodhi, 3, and Journey, 1); Green also has a son, 15-year-old Kassius, from a previous relationship.
But Green doesn't know if he's ready for another boy just yet, and noted he and Fox aren't necessarily trying for another child at the moment.
The 44-year-old actor discussed his desire for a daughter with Fox in a Facebook Live interview with Hollywood Pipeline on Monday.
He added, "I'm anxious that if I try, I'll just get another boy". 'Not just because I love my boys, but I'll have another boy and I don't know if I'm ready for five'. "So that would be kind of awesome".
