Adam Carolla is not a fan of Ellen DeGeneres.

“Ellen has always been a mean person,” Carolla, 61, declared during his appearance on “After Party with Emily Dashinsky” Tuesday.

The comedian claimed that when he was on DeGeneres’ former eponymous talk show, he witnessed her staff being “real scared” of her.

And I go, ‘Yeah, yeah,’” Carolla, who was on the show in 2012, recalled.

“He goes, ‘You’re not gonna talk about meat or beef or anything like that, right?” Carolla added. “And he came back 20 minutes later right before I went out, and he’s like, ‘OK, but don’t talk about beef or meat.’”

“I was like, ‘Oh, this guy’s scared to death,’” Carolla said. “This guy’s scared.”

Carolla alleged that another member of DeGeneres’ staff told him he hated working for her.

“Later on, I talked to someone who signed an NDA, so I won’t say his name, but he wrote for Ellen,” he explained. “I just went, ‘How’s Ellen?’ And he said, ‘Worst person, uh, worst person — not worst person I’ve worked for, worst person I’ve ever met.’”

Carolla added that the writer allegedly used to work for Rosie O’Donnell and said that DeGeneres was a far worse boss than O’Donnell.

“She’s not a nice person at all,” Carolla reiterated about DeGeneres.

“Everyone was scared of her, which means she’s mean,” he continued. “She’s not gonna be mean to me, I’m a guest on the show, right? I wouldn’t know it from my exchanges, I would know it from how her staff was cowering.”

The Post has reached out to DeGeneres’ rep for comment.

DeGeneres hosted her talk show from 2003 until it was canceled in 2022 following toxic workplace claims.

In 2020, current and former staffers spoke anonymously about their alleged experience on set of the talk show for a BuzzFeed News report. She apologized to staff at the time and producers Ed Glavin, Kevin Leman and Jonathan Norman exited the show.

DeGeneres  — who now lives in the UK with her wife, Portia de Rossi — touched on the controversies in her final stand-up special last year, claiming she was “kicked out of show business” following the reports of her alleged behavior.

Last April, she also joked at a show in West Hollywood that she became the “most hated person in America.”

Like Carolla, other stars including comedian Margaret Cho and “The Bachelorette” alum Ali Fedotowsky have called out DeGeneres for being allegedly cruel over the years.
