This little gem has never been seen before, and isn't even on YouTube yet. In the clip, Sel's singing with the big man himself, Barney. While most of us are usually worried about her duets with Justin Bieber these days, it's cute to remember how little Sel once was. Seriously though, how precious is she?!
There are rumors Selena will be celebrating her big day with friends at Disneyland. Reports say Justin won't be there to bring in the birthday fun, but you know how those two are! Guess we'll just have to wait and see.
Watch Selena get her sing on with Barney below. Happy birthday, Sel!
