Kevin Hart and Dwayne Johnson are both extremely successful and busy men. Between the two of them, they probably release more movies a year than anyone else in the industry right now. If you turn around there's a new Kevin Hart movie. Turn around again, a new Dwayne Johnson film. Turn around one last time and they're starring in multiple films together. When they're not churning out movie after movie, the two Hollywood stars are poking fun at each other on Instagram. 

Their most recent social media argument began when Johnson posted a photo of himself holding his newborn daughter. The hilarious part was, he replaced her head with Kevin Hart's.  "To my beloved son, @kevinhart4real," wrote Johnson before breaking into a rhyme. "Twinkle Twinkle little Hart, I just don’t know where to start. Daddy will always love and protect your tiny little soul, Even though you were delivered directly out of the butthole."

Not to be outdone, Hart responded with a photoshopped picture of his own. "He’s also a slobbering baby which is annoying as hell...I think it’s the protein shakes 😂😂😂 ....Also my post is funnier because you can tell that I just smacked the shit out of him in this photo," joked Hart in the lengthy post where he goes in on Johnson. 

Who do you think is winning this Instagram battle?
