Megan Fox wasn't kidding when she said she wanted to expand her growing family.

The new mom, who just gave birth nine months ago, is already up to baby number two with husband Brian Austin Green.

"I can confirm Megan is expecting her second child with her husband, Brian, they are both very happy," a rep for the actress told the New York Post's Page Sixon Friday.

Fox, who delivered her baby boy Noah last September, is currently in the middle of filming for the "Teenage Mutant Ninja Turtles" reboot in New York City, which is slated for release in 2014.

However, as much as she loves acting, she recently told Marie Claire UK that her heart is set on her family and having more children.

"All I wanted to do my whole, whole life was have a baby and, now, I've finally done it. I just want to give Noah as much of myself as I can. And I want to have more kids. That is where my heart is," said the "Transformers" actress back in March.

The 27-year-old and Green, 40, hit it off after they met on the set of "Hope & Faith" in 2004. They then became engaged in 2006. After a brief split in 2009, the couple renewed their engagement, eventually tying the knot in June 2010 in Hawaii.

"I feel like I'm with my best friend," Fox told MTV News about Green last year. "I've been with him for so long, so it feels natural and comfortable."
