Selena Gomez and some of her gal pals dance like nobody’s watching in a video shoutout to her BFF Taylor Swift. The girls whirl, twirl and shimmy to Swift’s “I Knew You Were Trouble” off her new album Red. Who knew Selena could be so hot!

The song seems appropriate in more ways than one for the “Spring Breakers” star.

Gomez reportedly has a rocky relationship with boyfriend Justin Bieber. The two are said to quarrel frequently and have broken up and made up several times. Justin didn’t help much when he got fresh with a bunch of Victoria’s Secret models at their annual fashion show.

He was especially cutesy with model Barbara Palvin and went out with her and a group of friends to catch a Broadway show. But at last count, Justin and Selena appear to have patched things up.

The video opens with Selena and three girlfriends Samantha Droke, Francia Raisa and Laura Quinn, dancing and laughing in a circle. Swift’s song blares in the background. But the video is more than girls having fun.

The scene quickly cuts to a dance studio and the four girls are doing a sexy choreographed routine. Selena wears a slinky sleeveless top.

“Me and my friends just goofing around to our favorite song,” Gomez explained. “I want to give a big thanks to my friend Gweny(Guynemer Caceres ) for choreographing this fun dance. My girls for being amazing and for Taylor being such an inspiration.”
