Megan Fox strips for "This is 40" movie trailer

In the upcoming movie ‘This is 40,’ Megan Fox flaunts her assets in a comedic scene with costar Leslie Mann.

In the trailer for the film, which is due to hit theaters in late December, Leslie Mann is seen poking at Fox’s chest while Fox is wearing only a bra and underwear.

“Are those real?!,” a slightly distressed Mann asks Fox in the trailer. “Yeah! I’m just young,” replies Fox. In the film, Mann’s character Debbie seems to be grappling with the realities of aging and marriage.

The film, dubbed a “sort-of sequel to Knocked Up” catches up with Debbie, played by Mann, and her husband Pete, played by Paul Rudd.

Also in the film are Irish American actor Melissa McCarthy and Roscommon native Chris O’Dowd, both who appeared in 2011’s comedic hit ‘Bridesmaids.’

More recently, Fox has been flaunting her new body - one with a growing belly bump. Her and her husband Brian Austin Green, who first met while filming the TV show ‘Hope and Faith’ are expecting their first child together.
