Dwayne Johnson, a.k.a. "The Rock," is not known for trolling other celebrities on the internet.
However, the affable actor does make an exception for his Jumanji: Welcome to the Jungle co-star, Kevin Hart.
And the ribbing which stems from their bromance borders on the uncomfortable and the oh-so-satisfying.
The two have gotten along famously since they teamed up for the first time in 2016's action-comedy Central Intelligence.
Blame it on their extremely opposed height differences, but Johnson capitalizes on his upper hand and teases the heck out of Hart, mainly by referring to him as his 'baby son.'
A recent example of this is from an October 12, 2018, tweet in which Johnson posted a picture of his two-year-old daughter, Jasmine, seemingly mesmerized by her father's workout.
"My lil' Jasmine Lia luvs watchin me clang & bang in the #IronParadise. Warms my cold black heart as she sits in awe..." he wrote.
And then he referenced Hart in the same tweet.
"Ironically, my baby son @kevinhart4real does the exact same thing too when watching his daddy."
Of course, the internet was all-a-Twitter over Johnson's dig at his vertically challenged co-star.
Kevin Hart, being Kevin Hart, responded with his signature, abrasive irreverence he reserves for those who hold a special place in his "Hart."
Now isn't that special?
Their hilarious camaraderie has been going on for a while now - since the comedian's birth, apparently.
Johnson was honored with the 2,624th star on the Hollywood Walk of Fame on December 13, 2017.
Hart couldn't resist going further than just a congratulatory shout out.
During a press tour for Jumanji in Paris, Johnson and Hart were all smiles. But The Rock wrote what went down after this cheerful photo op.
May their banter forever continue for our enjoyment.
