Shortly after the "Sorry" singer, 22, kicked off his Purpose World Tour, a string of questionable behavior began fueling headlines.
While a report intimated his tour was in trouble, in late-May, a rep for the singer called the rumor "bull---t," telling PEOPLE "he's totally fine."
Indeed, a source told PEOPLE at the time: "Two months into it, and he already feels beat. He's not losing it, though. He's just trying to find ways to focus."
With domestic and international shows scheduled through November, Bieber will be on the road for months more.
Below, a look at his antics in recent months.
June 8, 2016: TMZ posted a video of Bieber involved in a fist fight outside a Cleveland hotel on Wednesday.
June 7, 2016: A day before the hotel altercation, the pop star posted a photo on Instagram of him holding a fan's baby, calling the tot "my daughter" but saying he was "just kidding."
The same day, Bieber posted a photo of himself getting pedicures with his mom, Pattie Mallette, and pal Khalil. The outing seemed to be a reunion of sorts for Bieber, who said last year his relationship with his mom was "pretty non-existing." (Last month, an insider told PEOPLE: "People have always known you as a kid, and you want to grow up and do different things and not be seen as a kid ... What do you expect from someone who was on top of the world, with no proper home?")
Though he hasn't been seen with Mallette much this year, Khalil has popped up in Bieber's social media feed quite a bit in the past month. In January 2014, Bieber and the now-21-year-old singer were arrested in Miami after drag-racing in Lamborghinis; Bieber was charged with DUI.
May 11, 2016: Bieber hit up Storyville nightclub in Boston, where he kicked partiers out of a VIP room, danced on a bar while smoking a cigarette. The same night, he sat alone at a different bar, drinking a Jack and Coke and chatting with the bartender.
Earlier that day, Bieber held a hotel guest's baby at the Four Seasons and was spotted sitting in a tree in a Boston public park. ("Visiting parks and meditating calms him," a source told PEOPLE after photos from the park surfaced.)
May 10, 2016: Still in Boston on tour, the pop star was photographed walking around barefoot inside a park and outside of his hotel.
The same day, Bieber took to Instagram saying he refused to take any more fan photos moving forward because they make him feel like a "zoo animal."
At the time, a source told PEOPLE the photo ban was caused by an incident at a bowling alley in Boston shooting pool with a friend. During his game, he was approached by a family, who asked for a picture and implied they deserved one because they bought his album.
May 7, 2016: Bieber debuted a small, cross-shaped tattoo underneath his eye, inked by New York City artist Jonboy.
May 2, 2016: After Bieber posted a photo of himself with a tiger, PETA slammed him for the photo after the animal rights group alleged the tiger came from the Bowmanville Zoo, where owner (and Hollywood tiger trainer) Michael Hackenberger faces five animal cruelty charges when he was reportedly caught on camera whipping a Siberian tiger.
"Justin Bieber is lucky not to have had his throat torn out by this stressed captive tiger," PETA said in a statement
March 22, 2016: Bieber took to Instagram to cancel all future Purpose Tour fan meet-and-greets because "I end up so drained and unhappy."
