Every Artist Who Has Weighed In on Justin Bieber's Canceled Purpose Tour

Justin Bieber's now canceled Purpose World Tour has been the subject of a lot of debate, and everyone -- from Beliebers to fellow musicians -- has had something to say.

While some, including John Mayer, have expressed support of Justin's decision to call it before he could no longer take it, others have been more critical, pointing out that once you commit to something, you should stick with it.

Check out what other musicians had to say about the cancellation of Bieber's last 14 Purpose shows: 

John Mayer

John Mayer was one of the first artists to show support for Justin’s cancellation. On July 24, the very day Bieber publicly announced his decision to cancel the remaining shows, Mayer posted a series of tweets defending the young pop star. “When someone pulls remaining dates of a tour, it means they would have done real damage to themselves if they kept going,” he writes. “We’ve lost so many great artists lately.”

More recently, in an interview with Variety, Mayer further explained why it’s important that he and others support Bieber. "There are a hundred different reasons you can give for canceling a tour," he said. "I think the one that goes, 'I think I'm done' is the bravest and healthiest one." He continued to give credit to the young performer, saying, “You have to apply a certain amount of grace to younger people who are developing into that.”

Passion Pit 

Michael Angelakos of Passion Pit followed John Mayer's take on the decision, even retweeting his messages to Bieber. With so much happening lately, from the Manchester Arena bombing in May to the recent death of Linkin Park singer Chester Bennington, it's no wonder that musicians would be wary of pushing themselves over the brink. "Mental health awareness often just [leads] to... that," Angelakos writes, hoping to push it beyond awareness to acceptance and solutions.

Vic Mensa  

While Vic Mensa was financially affected by the cancellation of the Purpose World Tour, as he was set to open some of the final shows for Justin, he fully suports the Canadian singer's decision to take a break instead of pushing through till the end. Sometimes you need to catch a breath, and Mensa admitted to backing out of his own gigs before because of feeling like he "just can't do it"

Fifth Harmony

The Fifth Harmony ladies have Justin Bieber's back too. "We support him and support happiness," 5H's Normani Kordei told Entertainment Tonight. "He was on tour for about 18 months, so that’s a long time… He needed it." Lauren Jauregui added: "No one cancels a tour unless it’s damaging for them to continue, so he probably had a very good reason."

Louis Tomlinson 

One Direction's Louis Tomlinson -- no stranger to a grueling world tour schedule -- looked at the cancellation from both sides, telling 92.3 AMP Radio, "Obviously, you have to be in a good position mentally, but I also think, to a certain degree, when you're signing up to something, you should see it through."

Mark McGrath

Sugar Ray frontman Mark McGrath echoed Tomlinson’s sentiments in a video interview with TMZ, saying, although he isn’t in Bieber’s shoes, “the show must go on.” Listen to what other advice the rock singer has for Bieber below:
