Fans were quick to comment on the hilarious (but disturbing) mashup, writing things like, "Man, JB, you look GOOD!" and "Oh my God, DEAD!!!" The photo also received some major love from celebrities, including Patrick Schwarzenegger, Anwar Hadid and Scooter Braun.
Even Hailey, 22, weighed in, commenting, "Lolol I hate this," along with Justin's mother, Pattie Mallette, who said, "NO please make it stop."
Hailey isn't the only one Justin's been trolling, however. Earlier this week he shared a funny throwback photo of himself at Coachella with Kendall Jenner in 2015. "Coachella better be this good this year @kendalljenner," he wrote.
And so far, Kendall seems to be having a blast at the three-day music festival in Indio, California. On Friday, she was spotted in the crowd at Kacey Musgraves' sunset set alongside Hailey, who was rockin' a diamond-encrusted "Bieber" necklace. The two were also spotted at Jaden Smith's show on Saturday, where interestingly enough, Jordyn Woods made an appearance following her falling out with the Kardashian-Jenner clan.
