The rudest celebrities you'll be surprised to know

Let’s just agree we all love celebrities; the way they dress, talk, walk, or laugh, people are obsessed with them and why should not we? They're glamorous, charismatic and keep us entertain; in short, they are our ideals!

But beneath the spotlight's glow, some of the Hollywood stars are rude in real life, it’s hard to believe but it's the truth.

From actors such as Christian Bale to singers like Justin Bieber and Katy Perry; these A-listers have made headlines for all the wrong reasons; on top of all, for being rude.

Let's take a closer look at who's the rudest celebrity, based on fan reactions to their shocking behavior and unexpected interactions:

Justin Bieber

The Baby hitmaker’s bizarre interaction in public is an old news specially his erratic behaviour with paparazzi, however, once a fan tried to snap a selfie with Bieber just to get a rude response in return.

According to the fan, the singer told her that her lack of respect made him "sick".

Moreover, during a 2016 concert, the Sorry crooner allegedly spat on fans beneath his Toronto hotel room in 2013.

Later a representative claimed that nobody was below Bieber's balcony, and he didn't spit on anyone.

Christian Bale

The American Psycho actor, who is already infamous for being rude on the set of movies, is apparently not great off with fans either.

His former publicist revealed in her tell-all book that Bale is often awful when fans approach him.

According to her book, the Batman Begins actor would reportedly "lecture little girls about being rude and intrusive until tears streamed down their faces, and their parents tugged them away from our table."

Rihanna

Yes, you read it right! The Diamonds hitmaker in 2014 was shown her inspired prom outfit: a bat-winged pantsuit by a16-year-old fan named Alexis Carter, which she made herself.

The singer, who is expecting her third child, began tweeting side-by-side photos of herself and Carter.

The hashtag #PromBat took off, and Rihanna retweeted some of her favorite jokes, including "The Dark Thot Rises."

Carter later told Fox 45 News that she was very offended, telling the channel, "Why throw shade on it when you had on the exact same thing? The poses were different but the outfit wasn't... She don't love her fans like she says she does."

Ariana Grande

Sweet from the outside, rudest from the inside? In 2013, Dan O'Connor and his daughters, Jen and Kelly, were set to meet the 7 Rings singer when Jen won a contest.

Things took a shocking turn when after a long day of being shuffled around, they finally met Grande, who reportedly only spent 15 seconds with them.

They took a few photos, but Grande demanded they be deleted.

Jared Leto

Apart from acting in movies, the Morbius actor performs with his rock band Thirty Seconds To Mars, however, his patience apparently runs short in 2011 during his concert in Brazil.

Leto was onstage when one fan didn't know all the lyrics to his songs, so he reportedly gave her the middle finger.

Sean Penn

Penn, who has a history of violent outbursts, once showed his ire at a sales conference in 2013.

While in the lobby of the St. Regis Hotel in San Francisco, CA, Penn became enraged when another conference attendee tried to take a picture of him and in response, he allegedly grabbed the man's cell phone and threw it to the ground while screaming, "Do we look like f*cking zoo animals?"

Russell Crowe

The Gladiator actor was branded rude for scolding the talk show audience for clapping.

In 2015, Crowe made an appearance on the Irish talk show The Late Late Show and when host Ryan Tubridy convinced him to give the studio "something to tape our toes to," he scolded audience members who were trying to clap along. "If you're going to clap, clap in time. If you can't clap in time, just shut up."

Katy Perry

Yes, even Perry is on the list! The Dark Horse singer has been accused of trying to steal dancers from Taylor Swift’s Red tour.

“She basically tried to sabotage an entire arena tour,” the Anti Hero singer herself told Rolling Stone.

Moreover, one of the social media users once wrote on Redditor, “My cousin used to work in Hollywood and said Katy Perry was quite rude.”

Bad Bunny

The MONACO singer once grabbed a fan’s phone out of her hand and threw it into the bushes when she tried to get a selfie.

The king of Latin after the incident, clarified, “The person who comes up to me to say hello, to tell me something, or just to meet me, will always receive my attention and respect…Those who come to put a f–king phone in my face I will consider it for what it is, a lack of respect, and I will treat it likewise.”

Ben Stiller

The Night at the Museum actor is another actor being rude to his fans. “A friend of mine worked on the set of Tropic Thunder, and apparently Ben Stiller was a dick to everyone, he even fired someone because he thought they didn’t put enough sugar in his coffee in between scenes,” one Reddit user shared.

According to another fan, Stiller has been described as very entitled.

Nicki Minaj

Minaj during a particular exchange, was innocently asked by a fan when she’d be releasing a Pink Friday album cover. Nicki’s reply?

"Whenever I want to, when are you taking the next step in your education, boo?” So savage!" Her rude behaviour has also been witnessed on stage.

Ashton Kutcher

Kutcher has been branded the rudest celebrity not by a fan but fellow artist, Sharon Osbourne.

The TV personality once told E! News that the No Strings Attached actor is the rudest celebrity she's ever met, explaining that Ashton had a "bad attitude" because she mispronounced his name.
