We can't stop singing Ariana Grande's new single, 'Problem' featuring Iggy Azalea, and it looks like the rest of the world can't either! The bubbly singer has made history with the track, which has quickly become one of the fastest #1 debuts in history. 

When Grande officially released 'Problem' on iTunes yesterday, April 28, the tune skyrocketed to the top spot on the iTunes chart, scoring the coveted No. 1 position on the iTunes Overall Top Songs Chart -- in less than 40 minutes. That's some serious dedication, Arianators!

Needless to say, Grande was beyond thrilled, sharing her appreciation of and with her fans on Twitter, writing:

Not only did 'Problem' reach the top spot in the U.S., it also did so in 46 other countries, including Canada, New Zealand, Australia and Mexico, just to name a few. It also scored a position in the Top 5 in markets like Spain, Brazil and Argentina. That's international superstar status right there.

With all of the hype surrounding the new single, the 'Sam & Cat' star recently opened up about the inspiration behind the tune.

"[The song] represents the feeling of being absolutely terrified to re-approach a relationship that’s gone sour — but you want to more than anything,” she dished to Billboard. "In the song, it ends on a sappy, negative note, but in [real] life, we’re hoping it’s going to end on a positive one. I feel like it’s all very honest and human.” Of course, such a divulgence has left fans wondering exactly who the song is about, surmising that the tune was inspired by one of her exes, either Nathan Sykes of the Wanted or Jai Brooks.

Regardless of the BF who inspired the track, it's clear that the song has staying power, and we're glad that Grande is soaking up all of her success.
