After giving birth to royal baby Prince George, last month Kate Middleton was spotted out in her hometown of Anglesey, Wales where she flaunted her post baby body.

Prince William's wife stepped out, debuting a slim figure looking as if she did not recently welcome a child into the world.

On Monday, the Duchess of Cambridge decided to leave Prince George at home and head to her local Waitrose supermarket.

Middleton was dressed casually, wearing a black and white striped shirt paired with black skinny jeans and flats. The royal pulled her long hair into a high ponytail topped with sunglasses on her head.

The Duchess was spotted in the parking lot pushing a cart full of items showing a completely flat stomach just one month after birth, according to Us Weekly.

A source close to the family told the magazine, "She's hardly done anything to lose the weight . . . She looks incredible."

The source added, "Kate's still breastfeeding and the small weight she gained while pregnant has just melted off. She's not dieting. After giving birth, she did continue with her yoga."

For now Kate Middleton, Prince William and Prince George are staying in Anglesey until they move into their newly renovated 20-room Apartment 1A at Kensington Palace in September.

An insider revealed, "They've been in Anglesey for almost a couple of weeks and their lives are much more active there -- lots of walking, lots of time in the outdoors."

The source went on to say, "And the weather has been great. I'm sure they have been making the most of it."
