by Kristen HarrisBuzzFeedBuzzFeed StaffAs a staff writer at BuzzFeed, I write about all things celeb and pop culture.

I WISH I could name-drop the very famous author who was so rude to me that I never read one of his books again, but I don't wanna start anything. So, instead, I'll tell you about some celebs who were allegedly rude to other very famous people.

Here are 27 times celebs called out other celebs for being rude:

On the Sweet or Savory Podcast, Bretman Rock named Vanessa Hudgens as his "most disappointing celebrity encounter." He said, "I don't like her. ... I met her at Coachella, and we were both there for Sugarbear Hair. ... This was, like, young me — like, short hair still me. So I think, like, 2017 down, maybe 2018, even. But we have to go to the Sugarbear house to pick up our tickets to go to Coachella. She was there, and she was talking to the CEO of Sugarbear Hair, and I was friends with the Sugarbear Hair CEO. I'd been to his house, and we would talk and shit like that. And I remembered her talking to him, but obviously, I was trying to get his attention, so I'm, like, waving. I'm like — I forgot his name, honestly. Let's just say it was Chris. [I'm] like, 'Chris!' Like waving at him — not at her. And she literally looks at me and tries to hide."

"I'm like, first of all, I'm not saying hi to you... I'm not a fan. I was always Team Sharpay, let's just get that out of the way. Second of all, bitch, you're not even Mexican [for context, Vanessa, who is Filipina, played Gabriella, who is Latina, in High School Musical]. Like, you're not. You're not. You're motherfucking not. And third of all, bitch, I'm not a fan. She had a second person there. I think it was her assistant 'cause I don't know who she was. She grabs her hand and makes her stand in front of her to kind of, like, block, because at that point, like, I was walking toward them to say hi to the CEO of Sugarbear Hair, and that's why we're here," they said.

Bretman continued, "And you know how she's been dubbed as the 'Coachella queen,' whatever that means? I still don't give a fuck. I still don't give a fuck. I was not fucking saying hi to you, Vanessa. There's no reason for you to be hiding or having to have your assistant hide you because the only ones here are the ones invited. Girl, we have the same rate. It's not like you're getting an artist pass, and I'm getting a general. We're getting the same pass.

And I know time and place as somebody that has also been around famous people, especially at that time. Like, I know when to ask for a photo and when to not. And if you were to ask me if I've ever asked a celebrity for a photo, I have never. ... I'm like, 'Girl, you're not above me. I'm not under you.' And that's just that on that. And I'm literally like, 'I'm Filipino, bitch. You can't even, like, like your own people?'"

Vanessa Hudgens hasn't publicly responded to Bretman's comments.

Timothée Chalamet called out the disgusting "prank" his Interstellar costar Matthew McConaughey pulled on set. In a joint interview, Timothée told Variety, "I gotta say, my last day on Interstellar, I was sad to be leaving. In my trailer, I went to the bathroom, and there was a huge turd in my toilet. I felt so disrespected. Like, 'I know I'm not the star of this movie, but who's coming in here?' So I went around to all the grips, these big guys, and I said, 'Hey, one of you let it loose in my trailer.' They said no. I went up to Nolan, and he pointed to Matthew, and Matthew had this devilish grin on his face. I said, 'Why'd you do that?' You said, 'In Texas, it's a coming of age, baby.'"

Matthew simply replied, "Souvenir."

On The Bald and the Beautiful with Trixie and Katya, Kelly Mantle named Sofía Vergara as the "most rude celebrity" she's ever met. She said, "Maybe it was just a bad day. I'm just gonna say it was a bad day, 'cause she's hilarious and beautiful and talented and gorgeous and wonderful. So I'm sure it was just a bad day. We worked together on the set [of Modern Family], and it was not the most pleasant experience I've ever experienced. ... It wasn't toward me. It was the way that some of her staff was being treated."

She continued, "One of the big things was that, in the episode, she's wearing a wig, and so they kept wanting to put bobby pins in the wig. And she kept telling them, 'No bobby pins.' So, in the shot, they yell, 'Action,' and I'm supposed to put the crown on her hair. So I put the crown on, and then they say, 'Cut.' And she's like, 'Watch out for the wig. You're putting the crown on my head.' And I said, 'Well, girl, you should've put those bobby pins in.' ... It just came flying out of my mouth. So, but, you know, it was more than that, but that was one of the little things that h
