Kylie Jenner flaunts post-baby body in black underwear 1 month after giving birth

Kylie Jenner is bouncing back -- quickly!

The 20-year-old Kylie Cosmetics founder took to Snapchat on Thursday to show off her unbelievable post-baby bod just one month after giving birth to her first daughter, Stormi Webster.

Clad in a black crop-top and matching underwear, the former "Life of Kylie" star looks absolutely incredible as she poses along to a rap song in her mirror at home. She is rocking some serious black hair extensions in the clip, too.

Jenner had been spotted out and about since giving birth, but this is the first time that her physique has been on display. Though she's returned to social media since welcoming Stormi, she has yet to be as active on Snapchat or Instagram as she was before she became pregnant.

Also on Thursday, Jenner took to Instagram to celebrate one month since her daughter was born with a gallery post that included two photos of the new mom holding her baby in front of her garage door. Clad in a camouflage sweatsuit and Yeezy sneakers, Kylie looks fiercely into the camera as Stormi looks up at her in an animal onesie.

In the second, close-up shot, Stormi's face is visible for the first time as she grabs onto the zipper on her mother's hoodie.

Her sister, Khloe Kardashian, has definitely been more active on social media. The "Revenge Body" host has been rocking some seriously glamorous pregnancy styles as her bump continues to grow during her first pregnancy.
