Barely-there baby bump! On Friday, Aug. 2, Megan Fox's rep confirmed to Us Weekly that she's expecting her second child with husband Brian Austin Green. Despite her pregnancy, Fox has very recently been hard at work filming 2014's Teenage Mutant Ninja Turtles . . . and apparently concealing her burgeoning bump.

On July 24, Fox, 27, was photographed on the New York City set giving a glimpse of her tummy under her a tight blue T-shirt, yellow leather jacket and jeans. Between scenes, she was also photographed enjoying a popsicle -- possibly fending off her pregnancy cravings.

Fox and Green, 40, who wed in 2010, are already parents to 10-month-old son Noah Shannon. The former Beverly Hills, 90210 star is also father to son Kassius, 11, from his previous relationship with Beverly Hills, 90210 costar Vanessa Marcil.

Baby number two should come as no surprise: In the March issue of Marie Claire UK, Fox told the magazine she was ready to have more kids. "All I wanted to do my whole, whole life was have a baby and, now, I've finally done it," she said. "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."
