Cameron Crowe is set to become a father again at 67

According to PEOPLE, Anais shared on Facebook: "Baby Crowe is coming this Fall. So happy to share this exciting news!! Our hearts are overflowing with love & gratitude for this next adventure together, as Mom & Dad!

"We can't wait to meet you, baby girl. You've already added so much color, sunshine and love to our lives #thirdtrimester (sic)."

Anais also posted a number of pictures of the couple together, including one of him kissing her pregnant belly.

'Almost Famous' director Cameron already shares twin sons Curtis and William with his ex-wife, Heart guitarist Nancy Wilson.

The former couple welcomed the boys in 2000 and split in 2008, although they waited until 2010 to file for divorce.

Nany - who is now married to Geoff Bywater - told PEOPLE in 2021: "[The divorce] was really a sad time because I didn't know how to get through it. But now it's definitely okay, because what it brought to me was my new relationship with Geoff, which is everything I always wanted.

"I was holding out because I thought we could fix it. And I was from a family where my mom and dad were such devoted people. In my mind, I thought that was the standard by which my life should be lived and my relationships should meet up to. So, when it wasn't working, and I couldn't fix it, I was devastated."
