Jessica Simpson is busting out...literally.
The new mom tweeted a pic of herself in a low cut dress, while out pushing a pram with baby Maxwell on Friday.
"Just taking a walk around the block," Simpson wrote before asking "Street legal?" apparently about her revealing outfit.
Simpson and fiancé Eric Johnson became parents May 1.
They haven't yet set a wedding date. Jessica is first working on getting back into shape with the help of her $4 million Weight Watchers deal.
She's said she's not worried about getting back into a bikini, just jeans. And a wedding gown, no doubt.
