Megan Fox and Brian Austin Green are expecting their second child to join 9-month-old son, Noah.

“I can confirm Megan is expecting her second child with her husband Brian,” publicist Leslie Sloane Zelnick, told the New York Post’s Page Six. “They are both very happy.”

Green is also father to son Kassius, 11, from his relationship actress Vanessa Marcil. Fox, 27, and Green, 40, tied the knot in 2010 in Hawaii. The actress is on location in Manhattan filming “Teenage Mutant Ninja Turtles.” She's still in the “early stages” of pregnancy and has been attempting to keep the news a secret on set, a source said.

In January, Fox told Marie Claire UK, "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."

Fox said that motherhood has made her pickier about movie roles. “I’m going to be more cautious about choosing films,” she told the Hollywood Foreign Press Association last year about her sexualized onscreen persona. “I’m already thinking about when [Noah's] in school and his friends are going to be showing him my photo shoots with me in a bikini and he’s going to be horrified.”
