Jill Zarin received backlash from the "Below Deck" crew due to her behavior.

On Monday's episode of "Below Deck," the "Real Housewives of New York" star joined her pal, a primary guest, in a superyacht. However, she raised eyebrows due to her alleged diva behavior.

"Jill is the primary in her head. She's overwhelming," stewardess Barbara "Barbie" Pascual admitted in a confessional, Page Six reported.

"I think she's annoying, and I think it's too much. You're a freeloading guest who's extremely demanding. This is too much for me. I need another stew just for Jill."

Zarin requested a bell from Chief Stew Fraser Olender, so she could call them when she needed anything.

Based on the episode, Olender also didn't like the Bravo celebrity's behavior.

"Jill is crawling into my brain and eating away at my soul," Olender said.

Chef Anthony Iracane also shared the opinions of the other crew members. Iracane slammed Zarin, saying she was like a captain, and he even claimed that their prime guest was OK compared to her.

"I think the primary, she's OK, but her friend taking over the boat, it's like she's a f*****g captain," Iracane said in his confessional. "Like taking over the ship."

In the episode, Zarin demanded different-shaped ice cubes for her Diet Coke.

"I don't care about anyone else. My Diet Cokes [go] into the freezer," Zarin said.

She made a "special request" for a makeup mirror and pointed out the lack of an electrical outlet in the bathroom. She even criticized the bathroom because it wasn't stocked with toiletries.

"I want to tell you something else because I've charted a lot of yachts before [and] every bathroom is loaded with toothbrushes, toothpaste, mouthwash, Band-Aids, Q-Tips -- has anyone ever said that before?" Zarin asked Pascual. "I like to complain, I'm sorry."

She also voiced her concerns about the food being cold and the lack of hot sauce. She requested the chef to prepare a separate meal for her and suggested that the crew should be ready with snacks "all the time."

"That's why I have to get involved. I'm a little pushy, but at least you'll be satisfied," Zarin told the primary guest.

Many were turned off by Zarin's rude attitude after watching the episode. One viewer even said online she unfollowed the celebrity while watching the show.

"Watching #BelowDeck and just unfollowed Jill Zarin. I knew she could be a pain sometimes, but I thought overall as a person that she was kind and considerate. Clearly, I was wrong. My parents would be so ashamed of me if I treated [people] that way," one tweeted.

"Jill Zarin was a complete NIGHTMARE of a charter guest, and mind you, she didn't even pay for the charter #BelowDeck," another added with a laughing emoji.

"Every time Jill Zarin returns on a #Bravo show, we're reminded why Jill Zarin isn't regularly on any Bravo show. #BelowDeck #RHONY," a third person opined.

Page Six reached out to Zarin for comment but didn't receive any response.

"Below Deck" airs Mondays at 8 p.m. ET on Bravo.
