Ellen DeGeneres reportedly banned these celebs from 'The Ellen Show'

It appears as though not everyone is welcome at "The Ellen DeGeneres Show."

According to a new report in Page Six, there are a handful of famous faces who are "banned" from Ellen DeGeneres' daytime talk show, mostly for speaking out against gay marriage.

The reveal of the celebrities who are allegedly banned from the show follows the controversy surrounding DeGeneres' friendship with former President George W. Bush, which she defended by encouraging her viewers to befriend people with different beliefs than theirs and to "be kind to one another."

"Here's the thing: I'm friends with George Bush. In fact, I'm friends with a lot of people who don't share the same beliefs that I have. We're all different, and I think that we've forgotten that that's okay that we're all different," she said on her show. "Just because I don't agree with someone on everything, doesn't mean that I'm not gonna be friends with them."

So, despite Bush endorsing a constitutional amendment that would ban same-sex marriage during his presidency in 2004, DeGeneres formulated a friendship with him and even had him on her show in 2017.

Caitlyn Jenner, however, wasn't so lucky: The former "Life of Cait" star was reportedly banned from "The Ellen Show" after the 2017 release of her controversial memoir, "The Secrets of My Life," in which she said DeGeneres "alienated" her from the LGBTQ community as a result of her musings on gay marriage on her show in 2015.

"I have to admit that I remember 15 years ago, 20 years ago, whenever it was that the whole gay marriage issue came up, I was not for it," Jenner said at the time. "I am a traditionalist. I mean, I’m older than most people in the audience. I like tradition and it’s always been between a man and a woman and I’m thinking I don’t quite get it."

Notably, the rest of Jenner's family have made "The Ellen Show" a constant pit-stop when promoting their latest projects: Daughters Kendall and Kylie Jenner, as well as the entire Kardashian family, have appeared on DeGeneres' show countless times in recent years.

Comedian Sherri Shepherd's evolving public stance on gay marriage have also resulted in her reportedly being barred from the talk show. While she appeared on the first season of "Ellen," and subsequently made multiple other appearances, once she started to express that she was against gay marriage on "The View," the show "refused" to book Shepherd.

"When Sherri was on ‘The View,’ she used to get booked on the ‘Ellen’ show all the time. After she came out on ‘The View’ taking a stance against gay marriage, the ‘Ellen’ show refused to book Sherri. They never gave a reason but the writing was on the wall," a source told Page Six. "Ellen is obviously a hypocrite,” the source explained. “She said she can be friends with people who have different views from hers, yet she won’t give those people her platform and block them from appearing on her show."

As for Shepherd, she told the outlet that she's "unsure" why she hasn't been booked on Ellen's talk show in the last several years.

"I’ve always admired and respected Ellen. She was the first to book me for my first talk show, where I went on to hold a record 23 appearances; and she championed for me to be a co-host on ‘The View’ in 2007. The views and thoughts that I held have evolved from the statements I made on ‘The View’ over 10 years ago and I support same sex marriage and partnerships," she explained. "I am unsure why I haven’t been booked on Ellen’s show since my tenure on ‘The View,’ but I welcome the opportunity to reconnect with Ellen to thank her for her support and opportunities that have happened for me because of her."

Another person who has famously gotten into Ellen's crosshairs is Kathy Griffin, with whom DeGeneres has had a long-standing feud. While Griffin has been a vocal advocate for gay marriage and the LGBTQ community at large throughout her career, her tiff with Ellen is the reason why she said she was banned from her talk show.

DeGeneres sounded off on Griffin's comments in an interview with W magazine in 2007, saying, "I know she had a big thing about wanting to be on the show, and we didn’t book her. She did a whole thing that I banned her from the show. I didn’t ban her from the show, because first you have to be on the show to be banned."

Meanwhile, the 2011 trailer for Vince Vaughn's "The Dilemma," in which is character declares that "electric cars are gay. I mean, not homosexual, but my-parents-are-chaperoning-the-dance gay," was rumored to be the reason why Vaughn didn't appear on "The Ellen Show" for years.

It was CNN anchor Anderson Cooper condemning the line on "Ellen" that was allegedly the impetus for his ban. That being said, Vaughn has appeared on the show multiple times in recent years and a source told Page Six that they "love each other."

While Vaughn's ban was more of a rumor, gospel singer Kim Burrell's ban was confirmed by DeGeneres herself. After Burrell called gay people "perverted," Ellen blocked her from appearing on her show at the beginning of 2017, when she was slated to promote a song she made with Pharrell for the Oscar-nominated film "Hidden Figures."

"I actually didn’t know her, her name is Kim Burrell. She made a statement she was doing a Facebook Live and she said some very not nice things about homosexuals, so I didn’t feel that was good of me to have her on the show to give her a platform after she was saying things about me," Ellen said during Pharrell's appearance.

And, while George W. Bush is a rare exception to DeGeneres' alleged ban on celebrities who speak out against gay marriage or say homophobic remarks in a public forum, he's not the only one: Earlier in 2019, after Kevin Hart's homophobic tweets from years earlier reemerged online following the announcement that he would host the Oscars, he stepped down from the gig amid outrage from the public.

That same week, he appeared on "The Ellen Show," where DeGeneres launched an unsuccessful public campaign to get Hart reinstated as Oscars host, calling Hart's critics "haters." Naturally, it didn't go over so well.
