Justin Bieber Hits the Road With ‘Purpose’: Possible Guests Revealed

Justin Bieber drove the Beliebers into a frenzy as he officially started his Purpose tour March 9 in Seattle. The "What Do You Mean" singer hasn't been on the road for a long time and he wants to make sure that the fans will enjoy every minute of it. Taking a cue from Taylor Swift, Bieber also plans to bring some famous friends to the stage with him.

The 22-year-old "Love Yourself" hitmaker's tour will wind down in New York City on July 18.

Bieber hit list is so long that it's difficult to whittle down to a set list. Fans have expressed disappointment in not hearing some of his older music, especially hits like "One Less Lonely Girl."

“Currently he has no plans to change the set list,” the source told HollywoodLife . “The show is timed and structured in such a way that it will be difficult to change it up.”

But just because there's a schedule to follow doesn't mean Bieber won't try to shake things up.

“He is only interested in changing things up if and when guests come to join him on stage or if he adds more acoustic parts to the show,” the source added. “But as of right now he is going to ride his current set list.”

HollywoodLife previously reported that Bieber has reached out to Nicki Minaj to join him on stage. The duo will presumably perform their song "Beauty and the Beat." Other possible guests are Ludcaris, Usher, Carly Rae Jepsen and Tori Kelly .
