Music superstar Justin Bieber, known for his hit songs and successful career, faced a situation he couldn't handle. In 2015, Bieber begged UFC legend Ronda Rousey not to beat him up. The incident occurred after Rousey revealed that Bieber had been rude to her little sister at the Cannes Film Festival. Despite previously challenging Tom Cruise to a fight in the UFC, Bieber quickly backed down when faced with the possibility of confrontation with Rousey. He later admitted that his challenge to Cruise was just a joke.
