Being a celebrity comes with a great number of benefits - but with it comes a great deal of pressure as well.
Some handle it with aplomb, but others have a harder time dealing and just go off the deep end.
Here is a list of stars who cracked under pressure, highlighted by the Britney Spears Meltdown that will be discussed for decades to come.
Britney shocked the world in 2007 when she went into a salon and shaved her head completely bald. Word has is the hairdresser refused to do it, so she grabbed the clippers and did it herself. This was the culmination of a long-gestating mental breakdown.
You could almost say Charlie Sheen's entire adult life is a meltdown, but he peaked in 2011 when he declared himself a "warlock" with "tiger's blood" who was totally "winning." He wound up cussing out producers on his show Two and a Half Men, which led to his dismissal.
Kanye West's rants are stuff for the ages, but his Twitter tirades in 2016 led friends to suggest he needed mental counseling. After going off on Wiz Khalifa and Amber Rose, Kanye declared himself $53 million in debt and asked Facebook CEO Mark Zuckerberg for a loan. Shortly afterwards, he threw a widely publicized tantrum backstage during an appearance on Saturday Night Live.
Amanda Bynes alarmed fans by engaging in deeply erratic behavior starting in 2010, insulting other celebs on Twitter and announcing her retirement from acting. She was arrested after throwing a bong out the window of her New York City apartment and her mental health was questioned. Her mother finally assumed conservatorship over Bynes when she was placed on a 5150 hold.
After Mel Gibson was arrested for drunk driving in 2006, the actor unleashed a slew of antisemitic statements against Jews and called a police officer "sugar tits." Later, Gibson's ex-girlfriend Oksana Grigorieva released tapes in which he admits to abusing her and makes a number of sexist statements, racial slurs and even death threats against her.
Tila Tequila is another celeb whose mental health has been a concern, particularly in 2016 when she posted bizarre tweets claiming the earth was flat and that she had an alien brain. At one point, she begged for rent money on the social media platform - and actually got it.
