Among the Taylor Swifts and Miley Cyruses of the world today, it’s tough to make the list of Teen Queen, but always near the top is our girl Demi Lovato. Dems has been wowing crowds since she was a tiny tot belting it out alongside an imaginary purple dinosaur. Now as a veteran Disney princess, Demi is a full-fledged pop star who has worked stages all over the world. Thankfully, that includes the stage at the Teen Choice Awards!

That’s right — Dems will be performing at this year’s TCAs (as if we needed another reason to watch). She’ll join fellow headliners and X Factor alums One Direction in a night of such pop culture deliciousness we think we might get a contact sugar high.

Dems seems almost excited by the performance as we are (impossible, we know), tweeting yesterday, “It’s truuue!! I’m performing #MadeInTheUSA on the Teen Choice Awards!! Tune in to Fox on Sun. and get it on iTunes!!”

In between blasting us away with her latest summertime hit, Demi is nominated for six TCAs including in the category for “Choice Single: Female Artist.” Sure she’s already a multiple-time winner but another shiny trophy would be a totally awesome way to kick-off her birthday celebrations (Demi turns 21 on August 20). We’ll be rooting for you, Dems!
