Caitlyn Jenner on Monday reiterated her support for marriage equality.

“Like many people, there was a time when I didn’t realize how important it is for gay couples to have the right to get married,” Jenner wrote in her weekly column series called The Real Me. “But after hearing from my gay friends and learning more about the hardships they faced because of discrimination, it became clear to me that everyone should be able to marry the person they love.”

The support comes after she revealed during an interview with Ellen DeGeneres that she did not support such unions 15 years ago.

In the interview, DeGeneres questioned Jenner's conservative leanings, pointing out that many Republicans “would vote against all the issues that you as a woman and you as a trans person would want someone to support.”

Jenner, a Republican, admitted that when “this whole gay marriage issue came up, at first I was not for it. I'm a traditionalist.”

“You know, it's always been a man and a woman. And I'm thinking, 'I don't quite get it.' But as time has gone on, I think like a lot of people on this issue have really changed their thinking here to I don't ever want to stand in front of anybody's happiness. That's not my job,” Jenner told DeGeneres, who married actress Portia de Rossi in 2008.

“If that word, marriage, is really, really that important to you I can go with it, you know.”

“So, you're still kinda a little not on board with it?” DeGeneres asked.

“No, I'm on board,” Jenner responded. “Yeah, I'm okay with that.”

Appearing on The Howard Stern Show, DeGeneres said that Jenner “still has a judgment about gay marriage.”

“And I said, 'You're wanting people to understand and accept you.' This is like really confusing to people and you still have a judgment about gay people and marriage. She said if the word marriage is that important and I was like, 'It is, because that's the word,'” DeGeneres told host Howard Stern.
