At first my vote for the winner of Halloween was Demi Lovato. She had an amazing costume but she might have some serious competition. Dwayne The Rock Johnson and Kevin Hart may have the best friendship on social media. They are always doing movies together and they are constantly roasting each other. It is one of the funniest things you'll ever see. That dynamic continued for Halloween as Kevin Hart dressed up as The Rock from his infamous picture wearing a turtleneck and a fanny pack. The two also used this moment to promote their new movie "Jumanji The Next Level". In the clip you'll see Hart trick or treating at The Rock's house and pure comedy gold ensues.
