Barbie director Greta Gerwig announces she's expecting second child with Noah Baumbach

Barbie director Greta Gerwig joyfully announced Thursday that she is expecting a second child with her longtime love Noah Baumbach.

The power couple, who co-wrote the script for the upcoming Barbie movie, are already the proud parents of a three-year-old son called Harold.

Greta broke the news of her new pregnancy on The Tonight Show Starring Jimmy Fallon and noted she had been showing off her baby bump since last month. 

"I actually, I thought it would be - I went to an event recently and I wore something that I thought, everyone would be so interested to know that I was gonna have another child," she dished to talk show host, Jimmy Fallon.

"And nobody cared and it didn't get reported on, which turns out nobody's paying attention to you," Greta quipped.

Over the past few weeks she has been flitting from event to event promoting her new film White Noise, which she acted in and Noah directed.
