Selena Gomez and her pals make a music video to Taylor Swift's "I Knew You Were Trouble." It's AH-MAZING.

Have you heard that today's Taylor Swift's 23rd birthday!?! What better way to celebrate our favorite unofficial holiday (aside from making Taylor cat-friendly gift list) than by watching Selena Gomez and her BFFs DOMINATE some dance moves to the Red singer's latest single, "I Knew You Were Trouble." SPOILER ALERT: The video you are about to watch is EPIC. (Also, there is SO much sexy hair flipping, we can't even.)

 Watch Selena Gomez and her friends dance to Taylor Swift's "I Knew You Were Trouble." after the jump!

Selena and her pals' video homage to "I Knew You Were Trouble." starts all like,"hi we're just goofy friends singing along to one of our favorite tunes." Then it turns in to a full-on, flawlessly choreographed music video -- the ladies totally take on a girl band persona (complete with endless smizing, obvs).

But as much as we love that this video's dedicated to Taylor (the ACTUAL "I Knew You Were Trouble." video debuts today at 4:40 p.m. ET), part of us is wondering if this lil' video was also a little bit intended for Justin Bieber. Selena and Justin are technically still broken up (even if we're still VERY confused about their whole dating situation). But really, don't we all secretly fantasize about an ex seeing you look hot n' happy on the dance floor with your friends? On a really good hair day? We rest our case.

+ Watch Selena Gomez and her friends dance to Taylor Swift's "I Knew You Were Trouble.," and watch Taylor Swift's "I Knew You Were Trouble." video.
