You goooo, gurl!
Not only has Stars Dance had more sales in the first week than any of her other albums had in their first week, but it also became her first #1 album on the Billboard charts!
After selling just under 100k copies of her fourth album, Selenita will certainly be celebrating the success that's come after her seriously hard work and constant promotion.
But we can't help but wonder, will Justin Bieber be a part of that celebration?
Perhaps he'll make another special trip to see Selenita and pop some champagne bottles…
…gurlfriend is 21 now after all!
