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.
After kicking off his 2016 "Purpose" tour, the Biebs upset fans by canceling $2,000 meet-and-greets, explaining that they left him "feeling mentally and emotionally exhausted to the point of depression." He said the pressure of meeting people's expectations was too much for him to handle.
In 2011, the difficult actor threw a fit when a flight attendant asked him to shut off his iPhone during the plane's departure. He also blasted the city of New York when he received a ticket for riding the wrong way down the street on his bicycle, calling NYC a "carnival of stupidity."
Party girl Nicole "Snooki" Polizzi was arrested on the Jersey Shore in 2010 after she was "falling around, wobbling" around the beach and finally passed out face down in the sand.
Teresa Giudice lost her cool on season one of The Real Housewives of New Jersey and flipped over a table during a dinner party. We always kinda wanted to do that.
Reese Witherspoon was arrested for disorderly conduct in 2013 when her husband Jim Toth was pulled over for drunk driving. The actress got out of the car and talked back to police officers when questioned. Later, she issued an apology.
Chris Brown physically abused his girlfriend Rihanna in 2009, and that was enough to land him in the douchebag hall of fame forever. However, when asked about the incident on Good Morning America, he stormed off stage, ripped his shirt off and threw a chair into a window.
During a concert in March 2016 in Brisbane, the material girl reportedly took the stage late, chugged straight from a bottle of tequila, crawled around onstage, and even guzzled the mystery contents of a flask that she took from an audience member. She was reportedly heartbroken over the custody battle with ex Guy Ritchie over their son Rocco.
Lamar Odom overdosed in a Nevada brothel after a weekend of partying in 2015. He ended up in a coma and sources say he nearly died. His wife Khloe Kardashian has called his recovery a "miracle."
In 2012, Irish songstress Sinead O'Connor tweeted for psychiatric help, saying she was in desperate need of medication and in "serious danger." Later that year, she canceled a tour after a "serious breakdown" caused by bipolar disorder.
