The time has come to put on your favorite pair of Party Uggs, because Teen Mom 2's Chelsea Houska is celebrating her 21st birthday. OMG, guys, she's not a girl, not yet a woman. This is Britney Spears all over again!

There's no doubt that Chelsea has come a long way since popping Baby Aubree out of her lady parts at the tender age of 16 (sigh, those were the days...). Not only has Chelsea learned that bird feathers don't count as human hair, she's enrolled in beauty school, and she's finally over her baby daddy, Adam Lind. Girlfriend definitely deserves a drink. Or five.

Naturally, Chelsea has every intention of celebrating her birthday with friends and family, and she starts things off right by getting fake nails. Keep it classy, girlfriend! Of course, then Chel-Chel goes out to drinks with her besties to down some shots, but who should rain on her parade? The one and only Adam, who texts his baby mama in the midst of her bday extravaganza and accuses her of making out with a bunch of randoms. Um, jealous much, Adam?  

In other news, Chelsea has once again moved into a new house, because as we all know she lives a double life as a professional squatter. Hopefully she doesn't have any evil canine neighbors this time. Sob, never forget.
