Christian Bale
Christian Bale's roles in films like Batman and American Psycho have definitely painted him as a tightly wound guy. In 2009, a video surfaced in which Bale went on an explicit rant at Terminator Salvation director of photography Shane Hurlbut when the latter walked into Bale's eyeline during a take. After this incident, the actor was required to apologize profusely. Later, Bale allegedly yelled at young adoring fans and made them cry tears of disappointment. His career tanked quite a bit after this PR nightmare...
Ariana Grande
This Nickelodeon star-turned-pop sensation has had her fair share of issues in the limelight. Remember when she licked a donut then put it back? Yeah, not the best impression. Many fans might recall Grande's disastrous contest-winning meet and greet session in 2013. The singer only spent around 20 seconds with the contest winners before going back into her dressing room. Her team cited it as a "safety hazard" but the fans involved said that she just didn't want to speak to her followers.
