Paris Jackson's Past Concern for Justin Bieber, Plus More Artists Who've Opened Up About Touring Exhaustion

By

Justin Bieber is far from the only star who knows the toll extensive touring takes on one's health and well-being.

The "Sorry" singer's recent cancellation of the remaining dates on his Purpose World Tour, citing exhaustion, brings to mind the other musicians and stars who have spoken out both on the 22-year-old singer specifically, and their own experiences with doing dozens, or even hundreds, of back-to-back shows on multiple continents.

Most notably, Paris Jackson, who expressed concern this past January over Bieber's seeming state on the road, months before he would call it quits.

"He was tired, going through the motions," the daughter of the late Michael Jackson told Rolling Stone after attending one of the singer's shows. Jackson even went on to say that she was "scared" for Bieber, noting that the performance brought to mind "how my dad was exhausted all the time but couldn't sleep" during his This Is It comeback tour.

Earlier this week, John Mayer tweeted out a defense of Bieber's tour cancellation, offering his own firsthand knowledge of the damage overexertion can have on an artist.

"When someone pulls remaining dates of a tour, it means they would have done real damage to themselves if they kept going," Mayer tweeted on July 23. "We've lost so many great artists lately. I give Justin ???? for realizing it was time to call it. You should too."

Bieber's manager, Scooter Braun, echoed this sentiment in his own explanation for the cancellation.

"On behalf of myself, Justin, and the team, we are sorry," Braun wrote on Instagram. "A man's soul and well being I truly care about came first and We must all respect and honor that. Justin will be back and I know he looks forward to performing for you and with you all again."

And to those that won't be able to see it... on behalf of myself, Justin, and the team, we are sorry. That was never our intent. But a man's soul and well being I truly care about came first and We must all respect and honor that. Justin will be back and I know he looks forward to performing for you and with you all again. One chapter ends and another begins. Thank you again. Now please stop commenting on all my other photos that have nothing to do with this :) just kidding....but I'm not 😂.

And it's not just Bieber. Adele has a long history of opening up about her struggles with being on the road, most recently having to cancel performances in late June due to "medical advice" she received.

"To say I'm heart broken would be a complete understatement," the "Hello" singer penned in an emotional statement shared to Twitter. "It's highly unlikely I'd even make it through the set and I can't crumble in front of you all and walk out that way."

In the letter, Adele even admitted that she considered "miming" the performances, but could not give anything but the real her tofans. Ultimately, after 121 performances, Adele had to scrap her last two shows.

Prior to this candid admission, Adele had signaled to her fans that she was ready to stop touring.

"Touring is a peculiar thing, it doesn't suit me particularly well," the singer wrote in a letter that was shared to a fan Instagram account. "Plus I'm dramatic and have a terrible history of touring ... I only ever did this tour for you and to hopefully have an impact on you the way that some of my favourite artists have had on me live."

"I wanted my final shows to be in London because I don't know if I'll ever tour again and so I want my last time to be at home," the singer added.

💌😢😭✒❤Photo by Traci @tracii_m Translation by @wannabeadkins Adele @Adele's letter from her your book! "So this is it after 15 months on the road and 18 months of 25 we are at the end. We have taken this tour across uk+ Ireland, throughout Europe, all over America and I finally got to go to Australia and New Zealand too. Touring is a peculiar thing, it doesn't suit me particularly well. I'm a real homebody and I get so much joy in the small things. Plus I'm dramatic and have a terrible history of touring. Until now that is! I've done 119 shows and these last 4 will take me up to 123, it has been hard out an absolute thrill and pleasure to have done. I only ever did this tour for you and to hopefully have an impact on you the way that some of my favourite artist have had on me live. And I wanted my final shows to be in London because I don't know if I'll ever tour again and so I want my last time to be at home. Thank you for coming, for all of your ridiculous love and kindness. I will remember all of this for the rest of my life. Love you. Goodnight for now" ❤️Adele #Adele #Adelettes #AdeleLive2017

As much as an artist's connection with the audience is so much of what music is about, sometimes, you have to take your own well-being into account.
