Well her snap back didn't take long!

Kylie Jenner stepped out for the first time since giving birth to daughter Stormi over the weekend, and the reality star already looks like she's shed all the baby weight! We guess a post-pregnancy slim down is a lot easier when you're 20-years-old, but this was still record time!

It's not like the LipKit queen has been spending all her time in the gym, either! In fact, she can barely put her baby girl down to shower!

"Kylie is tired but getting used to the crazy hours. She is very attached to Stormi. She honestly just never wants to leave her out of her sight not because she can't trust anyone but because she just is so happy being with her baby," a source dished to E! News.

"She’s been crying tears of joy. She can’t believe she’s a mom. She hired extra security and she doesn’t want any strangers around the baby. She’s only allowing best friend Jordyn Woods and immediate family to meet her daughter. This is the first of many babies for Kylie. Nobody would be surprised if she has another one next year!” the source added.

We have a feeling a sexy selfie, or maybe even a bikini photoshoot, is coming!
