Justin Bieber keeping mum about huge world-wide tour which will feature Ariana Grande

“This is in the early phases but serious dialogues are taking place.”

Both teams have told their folks that they would like to make it occur, although nothing is finalized yet.

“They’d both perform their solo successes then team up together for a number of duets,” says the source.

“There’s a whole lot of crossover within their fan base,” another music source says. “If it will occur, it’ll be the top tour of 2016, pulling in countless millions for both vocalists.”

We are told discussions happen to be moving forward rapidly, although there’s been no official word on details from either artist’s team.

“It is Justin’s tour, so he’d start the show. Then they are able to determine what they will do and what they will perform collectively. They had probably link by the end of the show to get a hit.”

Bieber ‘s latest marijuana stunt did not appear to faze his supporters — the vocalist drank Hennessy during a recent show in New Zealand and smoked marijuana, reports TMZ. He was performing in a show in Auckland with hiphop duet Rae Sremmurd when he poured alcohol on the stage and lit a joint.

A source told the website that Bieber “did it on a challenge.” He is experienced Australia and New Zealand to market the record, apparently titled “Goal.”
