Congrats to Megan Fox and Brian Austin Green! The 'Teenage Mutant Ninja Turtles' starlet is pregnant with her second child.

The actress' rep, Leslie Sloane Zelnick, announced the happy news to Page Six. "I can confirm Megan is expecting her second child with her husband, Brian. They are both very happy."

Fox and Green are already parents to 9-month old son Noah Shannon. Green has an 11-year-old son named Kassius Lijah from a prior relationship with actress Vanessa Marcil.

Page Six reports that Fox is still in the early stages of her pregnancy, which allowed her to keep the news quiet when she was on set of 'TMNT.'

Fox is delighted to be a mom. She gushed about motherhood in March: "I recognize the blessings when they come ... the ultimate satisfaction for me is being with my son. 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."

Sounds like her heart -- and a few other things -- were in the right place. Mazel tov, kids!
