Sometimes it's not their fault. They're only human. Some stars have had anger-management problems; others have had addictions or other issues. And some were just jerks.
See the most regrettable moments from celebrities including Alec Baldwin, Ariana Grande, Justin Bieber and more.

NBC, which owns both shows as well as Trump's "The Apprentice," will cut ties with Bush soon, according to reports. This photo was taken in 2015.

The former child actress suffered a string of issues between 2012 and 2013. According to People.com, Byne faced DUI and hit-and-run charges in 2012. In 2013, suffering from unspecified mental-health issues, Bynes was placed under psychiatric hold in California in July 2013 after setting a small fire and behaving bizarrely in a stranger's driveway. Her mother was granted conservatorship soon afterward, and her lawyer in a DUI case said in September 2013 that she was unfit to stand trial. Bynes went on to complete inpatient treatment at a rehab facility.

In August 2013, the Amityville-born, Massapequa-raised Alec Baldwin scuffled with a photographer in Greenwich Village, pinning the man's arms back and pushing him against a car. Later that year, in November, after three more separate, heated paparazzi confrontations in just two days, Baldwin publicly apologized for using an anti-gay slur during one outburst. MSNBC suspended his recently begun talk show for two weeks, followed by the actor and the network announcing "a mutual parting."

The singer and former Disney Channel star had a string of bad behavior. In August 2013, she stripped to a skin-tone bra and panties, twerking against singer Robin Thicke and toyed with a large foam finger onstage at the MTV Video Music Awards -- and seemingly became the most talked-about person on the planet. After then appearing nude in the music video for "Wrecking Ball," an homage to Sinead O'Connor's "Nothing Compares 2 U" video, she made fun of O'Connor's acknowledged mental-health issues on Twitter, comparing O'Connor to the recently-hospitalized Amanda Bynes. Later that year, in November, in Amsterdam, at MTV's European Music Awards, she fired up an apparent marijuana joint on live TV.
Chris Brown(Credit: AP)
In 2013 August, singer Chris Brown had another 1,000 hours tacked to his community service for a 2009 assault conviction, with the judge saying Brown fudged documentation on the 1,400 hours he was supposed to have completed. Two months later, Brown and another man were arrested in Washington, D.C., after a 4:30 a.m. fight with a third. The singer quickly entered a rehab facility to address anger issues. He was subsequently kicked out of rehab, his probation officer says, on Nov. 20, 2013, after smashing his mother's car window during a family session.

Singer Justin Bieber had taken part in a string of bad behavior since 2013. He mooned fans on a quickly deleted Instagram photo on Jan. 19, 2013. In March, 2013, a video caught him nearly getting into a fight with a London photographer, screaming at the man, "I'll [expletive] beat the [expletive] out of you!" That same month, Bieber was thrown out of a Vienna nightclub after his bodyguards allegedly smashed patrons' cameras and cellphones and groped female fans. Soon after, The L.A. County Sheriff's Department investigated a battery complaint lodged against him by a neighbor who objected to Bieber's reckless driving on residential streets and reportedly was spit on by the teen. In July 2013, Bieber publicly apologized to Bill Clinton after he's caught on video cursing out a photo of the former president. According to CNN.com, Bieber was later photographed wandering around on Boston barefoot on May 9, 2016.
