Selena Gomez, Justin Bieber Back Together on New Single 'Strong'

Talk about a sneak attack! Pop singers Justin Bieber and Selena Gomez reunite and released new single "Strong" on OVO Strong Radio. It's unclear whose album it'll be featured on but the fans went crazy when the on-again, off-again couple set Twitter on fire with new music on Oct. 17. It was in the evening and no one saw it coming.

The heartbreaking love song is emotional, to say the least. Justin sings, "What should I do? Who do I talk to? Nobody knows," then Selena croons, "Wishing I was better at this damn thing cause it's just been too long and I can't change," Yahoo reported.

While the Biebs is trying to revive his music career and image, the pop princess admits to being a beleiber and seemed to cheer her ex on during a recent interview. She told New York Times. "While people were writing that I was stupid for being in [the relationship], this is what I always saw in him. Like, duh!" Gomez continued, "It's all part of my story. I'm growing and changing. I was in a relationship, and I was being managed by my parents, and I was still under Hollywood and Disney, and I was being held to this expectation of being the good girl."

Bieber's new album entitled Purpose and is due in-stores on Nov.13. It'll be his first album in 3 years:

Neither Gomez nor Bieber has commented about the surprise duet and we're still in the dark about when they recorded it. Fans are wondering if they have rekindled their relationship and will they perform in the near future?

Either way, two things are for certain: the super stars are in control and won't let nothing and no one stand in their way. When it comes to business, they've proven that they can set their differences aside and get the dough!
