Ariana Grande, Chris Brown, and More Stars Who Are Rumored to be Rude in Real Life

Jennifer Lopez acted like a "ghetto biatch," according to Rosie Perez.

Both Jennifer and Rosie worked together as "fly girls" on In Living Color back in the '90s. Rosie was a choreographer and Jennifer was a dancer.

“All of the girls were coming into my office complaining how [Jennifer] was manipulating wardrobe, makeup, and me, all to her advantage,” Perez wrote in her memoir, Handbook for an Unpredictable Life. “[She] went off [like] some ghetto biatch, screaming and pounding her chest! ‘You pick on me, me and only me, every f—ing day! Every f—ing day! I work my ass off, deliver and you keep pushing me aside, treating me like s—! I know I’m good! I’m better than any of these girls, and you know it.’ … I was blindsided. I’d thought we were cool."

Justin Bieber was a "d–k," according to Seth Rogen.

"He’s a good example of someone you meet, who you think you’re going to hate him, and then you get to hate him as much as you thought," he said on The Howard Stern Show. "You meet him, and he meets up to every one of your [bad] expectations of how you hope he will be."

"I went outside to meet him and he was acting like I asked to meet him! It was very nonchalant, ‘Yo man. Sup,’ and I’m like, ‘What the f–k, I don’t want to meet you. Don’t act all nonplussed to meet me. I didn’t want to meet you! I was totally cool not meeting you! … But I was like, fine, I wouldn’t have said anything, I was like, ‘Aye, he’s a bit of a motherf–ker. He’s young, the kid’s a dick.’”

Octavia Spencer acted like a "diva" at a book signing.

"Octavia was mean, rude and horrible to everyone," Octavia fan Angel Guzman said. "[She] was acting like a diva. She was mad because the event coordinator gave her a small glass of water but she wanted a large liter of 'good water' and demanded to know why she was being treated this way."

"A man approached with an 8X10 photo of Octavia for her to sign but she was clearly furious and said, 'I'm NOT doing that.' The guy was devastated, saying he bought it specifically for that day, that he was a big fan and he promised he would not post it on any social media outlets but she didn't care — she said 'absolutely not.'"

Octavia later laughed off the allegations.

Chris Brown was a "rude" neighbor.

"I think he’s a piece of s—,” Chris' neighbor Rudy Akbarian said. “He’s rude, first of all. I’ll come walking out with my friends at 12 o’clock. I get home at 12 o’clock from work. He’ll be out here with his stupid little friends and their stupid little cars, revving their engines. Like dude, people are trying to sleep! This is a residential area! You wanna rev your cars? Go to a frickin’ racetrack like normal people do. Not only that, it’s like the third or fourth time cops are out here. He doesn’t care.”

Iggy Azalea reportedly had a diva attitude on the set of House of Style.

"Iggy walked in with her entourage and wouldn't take her sunglasses off the whole time we were in the store shooting her," a production source said. "She had a complete scowl the whole time and never cracked a smile — unless the cameras were on. And the minute they stopped, it was back to scowling."

Lisa Vanderpump left a $5 tip for a $500 bill.

“She comes into Bar on 4 quite often,” a source who worked at the restaurant said. “She is always loud, and doesn’t treat any of the staff with respect. They ordered a ton of food and drinks and stayed for several hours. … They left $5 cash on a $500 bill!”

LeAnn Rimes was "annoying" at a concert.

"[During the concert] she talked for the next hour," KNIX radio host Matt McAllister, who was in the audience, said. "It’s just as annoying as if you’re in a movie and the person next to you won’t shut up. She talked like it was her show. I don’t know how to explain that. It was almost like she was speaking so loudly she wanted everyone to know she was there… she was singing the songs louder than he was.”

Cindy Crawford was fired for rude behavior on a Revlon shoot.

"It was on a Revlon shooting, and she was so rude to the whole team and the crew," he explained. He recalled how at one point Cindy said, "Why is Bruce photographing those old boxers when he could have been photographing me?"

"I didn't really feel for that," Bruce said about her remark. "I walked up to her and asked her, 'Did you say that?' [I told her to] get out of here."

Charlize Theron was "mean," according to Tia Mowry.

"She wasn't very nice to me. I said 'Hi,' and she actually rolled her eyes and said, 'Oh my God,'" Tia said. “I wasn’t over-the-top. I know how to approach another celebrity. Charlize was just mean. I'm just being honest."

Ariana Grande got "a kick" out of spitting on doughnuts.

“She was being rude,” Wolfee Donut owner Joe Marin said. “She was looking around, and that’s when I saw she was licking two of the donuts. Then she went to another tray that was on top and there was a tray of powdered donuts. So I zoomed [the camera into] her mouth, and the powdered ones, she did not lick them, she spit on those. She spit on one of them, and she dared that guy she was seeing and he spit on it, too. I saw they were getting a kick out of it and the two friends she brought, they saw what he did, too.” 

Jesse Eisenberg made an interviewer cry.

"So, I was just humiliated by Jesse Eisenberg," interviewer Romina Puga wrote on her blog. "When the five minute 'interview' (more like self-esteem butchering) were finally over I went behind a curtain to wait for the memory cards from the interview. I peaked around the curtain to ask Jesse about his neighborhood in New York (he lives a few blocks from where I used to live) and he immediately says, 'You’re still here?' … At this point I just wanted to go cry."

Kendall Jenner allegedly threw money at a waitresses' face.

Actress/waitress Blaine Morris tweeted about the incident, “That horrible moment you chase a Kardashian down the street because she forgot to pay her bill [only] to be thrown money in your face.”

Kendall denied the rumor and her lawyers sent a cease and desist notice to Blaine.
