Selena Gomez: Valentine's Day with Fans in Philly!

Donning a sparkly black dress, Selena Gomez rocks out with the crowd at The Gramercy Theatre in NYC on Thursday night (February 11).

The 17-year-old actress/singer looked to be having a great time and even had some special guests show up — American Idol‘s Katharine McPhee and Days Difference, who opened for her.

Selena sat down with MTV backstage and dished on her Valentine’s Day plans. She shared, “I have a show in Philadelphia, so I’m kind of excited. My fans will be my valentine, which is fine by me. And I’m really happy. I’m actually glad people are coming to the show, ’cause it’s Valentine’s Day … so hopefully I’ll enjoy a good show with my fans.”

She continued, “We have a lot of confetti, and I made sure it was pink and silver and stuff that’s very Valentine’s Day-esque. But other than that, I think it’s going to be an awesome show to be able to celebrate with my fans.”
