Family day out! Megan Fox shows off her post baby body while enjoying Malibu lunch with husband Brian Austin Green and sons Bodhi and Noah

They welcomed their third son together - Journey River - in August.

But Megan Fox and her husband Brian Austin Green left their youngest at home as they stepped out for lunch with sons Noah, four, and Bodhi, two, in Malibu.

The actress, 30, showed off her slim post-baby body on Monday just two months after welcoming Journey.

Megan revealed her fit form in sheer paneled navy cropped leggings.

The Transformers star added a black and white T-shirt that read: 'White wine is a hell of a drug.'

The mother of three hit the pavement in black, white and grey sneakers as she shielded her eyes with large framed sunglasses.

She styled her dark brunette tresses sleek and loose while opting for a makeup free face.

Megan held Noah's hand as she made her way into a local restaurant but carried Bodhi in her arms as they exited. 

Brian, 43, kept it casual as well; he donned a white T-shirt with black cropped sweat bottoms and bold Adidas sneakers.

The former Beverly Hills, 90210 actor sported a buzz cut and scruff for their daytime outing.
