The 44-year-old actor said he is keen to expand his brood - Noah, four, Bodhi, three, and 12-month-old Journey together - and would love nothing more than to give their three sons a sister, reported ContactMusic.
Speaking in a Facebook Live with Hollywood Pipeline, the "Beverly Hills, 90210" star - who also has son Kassius (15) with former partner Vanessa Marcil - said, "I don't know. I have four boys now, a fifth is a basketball team. So, that would kind of be awesome. I want a girl. I really want a girl."
"I'm worried 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.
