She's accomplished quite a lot in her young life!

Kylie Jenner turns 21-years-old at midnight tonight, and while we're sure she's got some over-the-top bash planned, she took the time today to gush on Instagram about how she already has everything she's always wanted now that she's a mom to daughter Stormi.

"Bringing in my birthday tonight with my most special gift. What was life before you, Stormi. I love you my little angel," she captioned a new photo of the pair.

Sister Kim let the cat out of the bag, though, that's there's a huge party planned for the LipKit queen!

"Sisters about to turn up tonight for Ky’s birthday!!!! *Don’t worry Kourtney included," she wrote on a throwback photo of all of them together.

Does her celebration include secretly walking down the aisle? Momager Kris Jenner hopes not!

“Kris is a little worried that Kylie might elope with Travis. He’s planning a special surprise for Kylie’s 21st birthday and Kris fears he might whisk Kylie off and marry her without any warning. Kris loves Travis and wants him as a son-in-law but she definitely wants to be there for the wedding," a source dished to Hollywood Life.

"Kris also wants to protect her billionaire daughter. She wants lots of advance notice of any wedding to get that prenup locked into place. The problem is Kylie’s very unpredictable and cannot be told what to do. If Travis asks her to elope for her birthday she may just say yes," the source added.

Happy Birthday, Kylie!
