A big world tour team-up with two of the world's biggest music artists is coming up in 2016.

Canadian superstar, Justin Bieber is reportedly planning a worldwide arena tour next year with singer-actress, Ariana Grande, according to reports.

As Bieber gears up for the upcoming release of his fourth studio album 'Purpose', reports say that Ariana Grande will be joining him on some of his tour dates across the U.S.

"The whole thing will hopefully end in several (U.S) stadium dates with special guest Ariana Grande," a source revealed. "This is in the very early stages, but serious conversations are taking place."

Reports say that the two will be performing their solo tracks, then several duets will follow after.

One source also commented about their possible team up, saying "There is a ton of crossover in their fan base. If it does happen, it will be the top tour of 2016, pulling hundreds of millions for the two singers."

The source went on saying, "It's Justin's tour, so he would open the show. Then they can decide what they'll perform together and what they'll do solo. They'd likely unite at the end of the show for a hit."

Since Bieber's return to the spotlight, the young superstar has been trying so hard to never miss a thing when it comes to putting his best on the new projects he's currently into and the big projects that he is about to make, such as his upcoming world tour collaboration with the 'Problem' singer.

Though Bieber is obviously soaring high in his career following his big comeback, he just couldn't get rid of a little downside. Reports say that Bieber has been throwing a shade against the four-piece band One Direction for having a same day release on their upcoming albums.

"They're not really going on the road much, but we're talking about them right now, so it gives them some promo, right?" he said.

He added, "So, that's probably why they did it, I think it was a strategy on their part because my release date was first. But whatever. It's going to be fun. I'm excited to see what happens."

Justin Bieber's 2016 world tour announcement will take place after the release of his upcoming album 'Purpose' on November 13, Friday.
