The Rock posted a photo Wednesday of himself in the gym while on location in China, and posed with his back turned to the camera, showing off his massive upper body.
The "Hobbs & Shaw" star captioned the photo by writing, " I find my church everywhere I go. #sweatequity #teamnosleep #china ."
The 47-year-old former WWE wrestler can be seen wearing a way too small red tank-top that happened to grab the attention of his "Jumanji" co-star.
40-year-old Hart couldn't keep his reaction to himself and left a comment on the post by joking, "Get a bigger tank top man....it looks like your wearing a thong on your back. I’m reporting this post...I’m sick of it!!! P.S congrats on the big opening...you deserve it you piece of donkey shit."
Hart and The Rock have starred in many films together over the years, and are constantly ribbing each other on social media.
In 2017 they did a segment for BBC Radio 1 where all they did is insult each other for four and half minutes. It was hilarious.
The Rock is currently in China promoting his film "Hobbs and Shaw" and wherever he goes, he makes sure a gym is not too far away.
He also seems to enjoy being a MASSIVE star in Asia.
After a presser with the Chinese media, Rock wrote, "Thank you China journalists for another great press conference. Very thoughtful and engaging questions about life, balance, success & how much food I actually consume in one day ."
