Selena Gomez And Demi Lovato Are Prom Crashers

Selena Gomez and Demi Lovato

It isn't everyday two of Hollywood's hottest young stars take a twirl around the dance floor at prom — unless it's on a soundstage with cameras rolling. But there were no cast or crew to be found last week when "Princess Protection Program" actresses and real-life BFFs Selena Gomez and Demi Lovato crashed the Etobicoke Collegiate Institute prom in Toronto.

According to People, Selena snuck out of a dinner celebrating the "Princess" premiere to take a walk around the complex when she stumbled upon the in-progress prom. She asked security if she could take a peek, and once inside, began dancing with a group of girls.

"They were all dancing in a group and having fun," a witness told People. "Selena was thrilled to see firsthand what a real prom is like and that her dress was much like the other girl's dresses."

When the "Wizards of Waverly Place" star returned to dinner and told bestie Demi about her prom romp, the two, joined by four friends, went back for more, dancing until 11 p.m. when they were asked to leave (because, you know, they weren't actually students).

Despite having her boogie night cut short, Selena Tweeted, "PPP peeps and I crashed a prom tonight and danced with a highschool!! amazing!! I finally had prom!"
