There’s nothing like celebrating the big 2-1 in Las Vegas.

Teen Mom 2 star Chelsea Houska turned 21 this past August and had a birthday party Saturday at the Pan Asian restaurant Social House, located inside Crystals at CityCenter.

Chelsea reportedly arrived at the Vegas hot spot around 8 p.m. and was escorted to her table, where she was joined by four of her closest friends.

The group got to dine on delicious-sounding food like Yellowtail Crispy Jalapeno Sashimmi, Black Cod Bibb Lettuce Cups and Kobe Hanger Steak — all paired with a bottle of Riesling wine. (Ah, the benefits of being legal!)

There’s more. Chelsea also got to indulge her sweet tooth, choosing from desserts like Mochi Ice Cream, Dark Chocolate Lava Cake and Yuzu Frangipane, which is a kind of almond cake.

We’re drooling. Obviously we should’ve been invited — to at least take home the leftovers!

Chelsea deserves a little pampering since, as we noted last week, she’s about to have knee surgery, after tearing her ACL for the third time.

Happy birthday, Chelsea — and good luck with the surgery!
