Whoa baby! Kim Kardashian and Kate Middleton had the world buzzing over their dual pregnancies this summer, and now, just months after giving birth in June and July, the first-time moms (who originally had the same due date for kids George and North) are ready to show off their impressive post-baby bodies.
On Friday, Oct. 18, Middleton revealed a slender figure while out at a SportsAid Athlete Workshop at London's Queen Elizabeth Olympic Park, where she showed off her volleyball skills -- and a flash of her bare, flat post-baby tummy.
The Duchess, 31, wore a striped black-and-white top, navy-blue military blazer and cropped J Brand jeggings as she made her way across the court, spiking the ball and gamely smiling for the cameras as she wore (and jumped around in) impressively tall wedges.
"She was a natural," 18-year-old Toby French, a volleyball player from Chelmsford, told Us Weekly of Middleton (she gave birth to son George on July 22). "You can tell she's sporty. She said she's played a little before."
A Middleton family source told Us that the mom has "hardly done anything to lose the weight … she looks incredible."
"Kate's still breastfeeding and the small weight she gained while pregnant has just melted off," the source continued. "She's not dieting. After giving birth, she did continue with her yoga."
Kardashian, meanwhile, made her much-talked about body reveal just two days earlier, sharing a glimpse of her post-baby curves in a very revealing white one-piece swimsuit selfie.
In the shot, the 32-year-old reality star flaunts her famous booty and plenty of side-boob while glancing seductively over her left shoulder. (Though both Kardashian and Middleton have been out and about since giving birth, these are their most revealing photos to date.)
"She is eating lots of lean proteins, healthy fats like nuts and avocado, carbs, fruits, veggies and cheese," a rep for Atkins told Us. "She wanted to be a healthy, nursing mom and not toxify her milk with her diet or lose weight too quickly."
Kardashian welcomed her daughter with boyfriend Kanye West, 36, on June 15.
