Ariana Grande turns 21 today!

But don’t expect to see her make her legal debut at a club or bar … instead the “Problem” singer spent the day with family and friends at Disney World.

On top of that, she’ll be giving her fans a gift: Her next single with Zedd, “Break Free,” will also be out next Wednesday.
