The 31-year-old singer tweeted a photo of herself with baby girl Maxwell Drew on a neighbourhood stroll but it’s her two fellow travellers that have been getting all the attention.
"Just taking a walk around the block," Jessica tweeted. "Street legal?"
We'll leave it up to you to decide if she really is a "yummy mummy".
Jessica recently signed a $4 million Weight Watchers deal and plans to lose 23kg of baby weight in five months. Although she initially cried about the challenge of losing the weight, the Fashion Star judge is positive about getting back into shape.
"The cool thing about the [Weight Watchers] program is that it focuses on healthy habits for the long term (and I can still indulge in my guilty pleasures every now and then, too)," Jessica wrote on her Facebook page.
"I have actually gotten a group of friends together who are going to do it with me."
Awesome, Jessica. Just don't tweet us every nook and cranny, okay?
