"Of all the things my best friend @KevinHart4real can dress up as for Halloween.
He comes back from injury to stick me with this dirty, rotten, HEARTLESS LOW BLOW. 💔😂
Love ya brother. Good to have you back," Johnson said in his own Instagram post.
The injury to which Johnson refers happened in September when a friend lost control of Hart's 1970 Barracuda and crashed the vehicle. Hart, who was in the front passenger seat, and the driver were seriously injured. A back seat passenger was also hurt, but not as badly.
Almost two weeks after the accident, Johnson took Hart's place on the first episode of "The Kelly Clarkson Show" and provided the audience with an update on Hart's condition.
Hart and Johnson have appeared together in "Central Intelligence," "Jumanji: Welcome to the Jungle," and "Fast & Furious Presents: Hobbs & Shaw," and will reunite in "Jumanji: The Next Level."
