If you're filming a movie with Dwayne Johnson, you're in for a hell of a time - just ask Kevin Hart. On Tuesday, The Rock shared a video on Instagram from the set of Jumanji showing him congratulating Kevin on his new movie, Kevin Hart: What Now?, by driving up on him and "scaring the sh*t out of him." "Got em! Funniest part of this is @kevinhart4real' producing partner @hgoodspeed covers his mouth after he sh*t himself a little. 😂😂," he captioned the clip. It's safe to say that these two are having a blast working together.
