Selena was on stage Washington, D.C. at the weekend when she noticed a fan in the front row on FaceTime.

Being the incredibly cute diva she is, Selena whisked the phone on stage to have a quick chat with the person on the other end.

"Did you guys not buy a ticket or..." she said while holding the phone up in front of thousands of people.

Sel was in great spirits the entire night and killed her performances - maybe it's because her ex Justin Bieber just refollowed her on Instagram?
