Greta Gerwig, Noah Baumbach welcome second baby

Director couple Greta Gerwig and Noah Baumbach have become parents to their second child, a baby boy.

Gerwig, who is awaiting the release of her film Barbie which she co-wrote with her partner, told fashion magazine Elle UK that she gave birth four months ago.

"He's a little schmoo. That's very much his energy. He's a wise little baby. I'm still doing that thing where I wake up every hour to 90 minutes and just hover. You just keep wanting to look at that baby," she said.

Gerwig and Baumbach, who have worked together on several films such as Frances Ha and White Noise, have been in a relationship since 2011.
