These days, "tweeting," is almost mandatory for celebrities. After all, Twitter is a incredibly useful tool for social networking whether you're famous or not. (Follow us here.)
Sometimes, though, celebrities can get a little carried away. Maybe they'll make an insensitive joke or a careless remark, or they'll accidentally post something they never intended anyone to see. Everyone screws up, including celebrities — and it's a lot more interesting when THEY do it.
Here are some infamous celebrity Twitter faux pas:
Who knows what actress Alison Pill was trying to do when she accidentally tweeted a topless photo of herself in September of 2012. The actress, who currently stars in HBO's "The Newsroom," quickly removed the photo and acknowledged her mistake, saying, "Yep. That picture happened. Ugh. My tech issues have now reached new heights, apparently. How a deletion turned into a tweet... Apologies." Pill's fiancé, actor Jay Baruchel, apparently found the whole thing quite amusing. "My fiancee is an hilarious dork," he later posted to his Twitter page. "I'm just glad it didn't happen to me first."
After seeing Jason Biggs have sex with an apple pie in his first major motion picture, you'd think America would be numb to his obscene antics. They're not. In August of 2012, Biggs posted misogynistic and sexually explicit tweets about Ann Romney and Janna Ryan on his Twitter page, prompting public outrage.
"How do you fire Jo Pa? #insult #noclass as a hawkeye fan I find it in poor taste." That was the tweet posted by Ashton Kutcher back in November of 2011, after he heard that Penn State's football coach, Joe Paterno, had been fired. Kutcher would later fess up to posting that tweet before learning the reasoning that Paterno had been dismissed amid a scandal involving the cover-up of child sex abuse at the university, and later tweeted, "This is an insane story, I just heard paterno was fired, getting the rest of the story now,” and “Fully recant previous tweet! … Didn’t have full story. #admitwhenYoumakemistakes.”
Al Roker didn't technically break any laws when he tweeted a photo of potential jurors during a jury screening at Manhattan Criminal Court, but he found himself in the doghouse with couthouse officials just the same. David Bookstaver, a spokesman for the court system, called Roker's tweet "ill-advised," although he acknowledged that Roker didn't break any laws as the photograph didn't depict any actual jurors or the inside of a courtroom. The incident, which took place in May of 2009, led Roker to later tweet, "I'm not breaking laws … just trying to share the experience of jury duty. One that I think is important and everyone should take part in."
Comedian Gilbert Gottfried was fired from his voice-over gig (as voice of the Aflac duck) for posting jokes on his Twitter account following the 2011 earthquake and tsunami in Japan (which is where Aflac does 75 percent of its business). Gottfried later apologized, saying, "I sincerely apologize to anyone who was offended by my attempt at humor regarding the tragedy in Japan."
In April of 2010, Kim Kardashian got a bit too excited about her seatmate on a flight from Los Angeles to New York. "I am sitting next to an Air Marshall!" tweeted Kim, adding, "Jim the air marshall makes me feel safe!" Twitter users soon informed her that she shouldn't be revealing the identity of an air marshal (a job where anonymity is crucial), but she didn't seem to care. "RELAX I just told u guys the Air Marshall is sitting next to me, highly doubt anyone is twittering like me on this flight!"
In December of 2011, Alec Baldwin sent out a slew of angry tweets after getting booted from an American Airlines flight after refusing to stop playing "Words With Friends" on his mobile phone. He first said, "Flight attendant on American reamed me out 4 playing WORDS W FRIENDS while we sat at the gate, not moving." He later continued his angry rant, tweeting, "#theresalwaysunited Last flight w American. Where retired Catholic school gym teachers from the 1950's find jobs as flight attendants."
Actor and self-proclaimed "winner" Charlie Sheen apparently wanted to become best buds with pop star Justin Beiber back in December 2011. That's when Sheen tweeted a message containing his personal phone number ("310-954-7277 Call me bro. C") to ALL of his Twitter followers, rather than just Beiber, which is what he intended.
Actor Dean McDermott should have taken a closer look at the Twitter pic he posted back in November, 2011. What he thought was just a silly photo of his son actually contained much more: his wife, actress Tori Spelling, was lying topless in the background.
U.S. Representative Anthony Weiner resigned from his post after accidentally tweeting a photograph of his groin — which was intented for a 21-year-old female college student in Washington — to about 75,000 of his Twitter followers instead.
Angered by the shooting of Trayvon Martin in February 2012, filmmaker Spike Lee retweeted the home address of Trayvon's shooter George Zimmerman — or so he thought. Lee actually retweeted the address of Elaine and David McClain, an elderly couple who had a son with a similar name as Zimmerman's. As a result, the McClains were forced to move to a hotel to avoid harassment. Lee later apologized on Twitter, writing, "It was a mistake. Please leave the McClain’s in peace. Justice in court."
AnnaLynne McCord, best known for her role as Naomi Clark on The CW's "90210," gave her fans an eyeful in January of 2012 after accidentally tweeting a photograph of herself containing (gasp!) a nipple. From the caption ("This is for you @meganraee You rock! Xxx A.”), McCord allegedly meant to send the photo to a single follower. After realizing her mistake, McCord reposted a tastefully-cropped version of the same photo.
