Selena Gomez is currently promoting her new single, "Come & Get It," but soon she'll be at the Radio Disney Music Awards (along with Justin Bieber, just saying), and then in August she starts her massive world tour.

But before she goes on tour, she'll turn 21. The big day is July 22. What is she going to do for that milestone event? Prepare to be ... underwhelmed! Selena doesn’t think it’s a big deal. “I mean, I think me and my mom were just gonna kind of plan something," Selena told On the Air With Ryan Seacrest, "but I don’t really think it’s gonna — of course, that aspect of being able to order a drink or something, but I’m pretty sure nothing’s going to change."

And even the drinking thing isn't that big a deal on her tour, since she starts in Canada (JB's home country, just saying) where the drinking age is already under 21. Still, it's pretty exciting to be a twentysomething as opposed to a teen or just a 20-year-old. And going on a world tour is its own massive b-day present!
