Last week it seemed as if Josh had spilled the beans about the gender of his unborn child during a recent interview, according to Gossip Cop.
Josh said, “You know your kid is going to get – he’s going to fall and bump his head. And he’s going to do all of those things. But that to me is going to be the hardest thing.”
The actor added, “Now I get to relive my youth through my child and see my child live all that. So everybody’s got a different path. I wouldn’t change anything. We’re completely happy. We’re much wiser than we were 10 years ago. We’re much more ready. I think we’re so strong as a couple and all of those things are really important when you bring a little one into the world.”
Oops, we wonder if Josh did let it slip?!
