May 20, 2014: Cannes Film Festival
The Situation: The Biebs walks the streets of Cannes, looking rather sad while occasionally tugging at his crotch.
Unnecessary Shirtless-ness Rating: 5. Bieber is seemingly the only one walking through the film festival crowd without a shirt on, but it looks like a nice day, and how often do you have the opportunity to be shirtless in France? Cut him some slack.
May 19, 2014: Gotha Club
The Situation: Justin is hanging out at the Gotha Club in Cannes, rap-battling Wesley Snipes and chilling with Rick Ross. "All smiles," Bieber tweets, perhaps while shirtless, perhaps while not shirtless.
Unnecessary Shirtless-ness Rating: 7. A classic situation of Bieber being shirtless in a room where no one else is shirtless. Despite the fact that his shirtless-ness is not altogether warranted, one can reasonably deduce that Bieber wanted to intimidate Snipes during the rap battle, and decided that his six-pack would help him do the job.
May 12, 2014: Hollywood Horseback Ride
The Situation: Bieber chooses to ride a horse during some L.A. downtime, calling himself a "young Indiana Jones" on Instagram.
Unnecessary Shirtless-ness Rating: 2. He's outside, not bothering anybody and wearing a hat to protect his face from sunburn. Go West, young pop prodigy!
February 5, 2014: Vanquish Nightclub
The Situation: Bieber parties with Diddy and Rick Ross in Atlanta, weeks after being arrested on suspicion of DUI.
Unnecessary Shirtless-ness Rating: 8. Considering the close proximity to a high-profile arrest, Bieber should have been keeping his profile low, not ripping off his shirt in a club while Rozay looks on approvingly. Look at how great Ross' shirt is! Why wouldn't Bieber want some of that shine?
July 21, 2013: Cabana Pool Bar
The Situation: More shirtless partying, this time in Toronto with various pals and bikini-clad ladies. Meanwhile, in Los Angeles, ex-flame Selena Gomez celebrates her 21st birthday.
Unnecessary Shirtless-ness Rating: 3. Hey, maybe Bieber was torn up about Gomez's birthday, and needed to fully express himself in the most clothes-free way he knows. Bonus points for the situation being an outdoor pool party.
March 25, 2013: Wladyslaw Reymont Airport
The Situation: Bieber inexplicably tosses his tee while walking through an airport in Poland, and is photographed going through a security checkpoint sans shirt. An airport spokeswoman confirms, "He wasn't told to take off his clothes."
Unnecessary Shirtless-ness Rating: 10. Simply unreal shirtless-ness, and it came in the middle of a series of bizarre incidents during his Believe tour. The only way Bieber could top this one is if he showed up to his own wedding with a bare chest.
