Yep, you read that right, she said 10 years. In case you didn't know, Selena and Demi met on the set of Barney and Friends like a bazillion years ago. Flash forward to today and Selena and Demi are tight as ever. The best friends each star in their own TV show now, Selena as Alex Russo on Disney Channel's Wizards of Waverly Place and Demi as Sonny on Sonny With a Chance, but Selena is quick to point out how much the big purple dinosaur taught her about working on a TV show.

"I learned everything from Barney," Selena said. "I learned what a prop was, what a producer did, what camera right means, camera left...and I think the whole experience of it was a good learning thing for me and I really appreciated that show and I miss it very much."

One thing she probably doesn't miss from her Barney days - singing the same songs over and over. Which song does she remember most? "Probably the brushing my teeth song I had to sing," Selena said. "It was really funny. I probably sang that on three different episodes."

So there we were, just hangin' with Selena. It was awesome. We were just trying to remember every last word she said so we could tell you guys everything when suddenly Selena's "people" said it was time for her to go.

And before we could even say "Twitter us!", our hang-time with Selena was over. We watched as she pulled an Alex Russo and disappeared in a flash, heading for Manhattan's stylish Soho district for a day of shopping with her cousin. And boy does Selena deserve it. With three movies coming out (Princess Protection Program, Wizards of Waverly Place: The Movie and Ramona and Beezus), a third season of Wizards she starts taping in August AND a solo album due in September...she might not have to worry about watching herself during tonight's PPP premiere after all. We bet she'll fall asleep as soon as she hits the couch!
