Anderson Cooper has, at long last, publicly said he is gay.

Cooper made the announcement in an email to writer Andrew Sullivan.

"The fact is, I'm gay, always have been, always will be, and I couldn’t be any more happy, comfortable with myself, and proud," he wrote.

Cooper's sexuality has long been the subject of ample media speculation, but he has never publicly confirmed it.

“I just don’t talk about my personal life," he told New York magazine in 2005. "...The whole thing about being a reporter is that you’re supposed to be an observer and to be able to adapt with any group you’re in, and I don’t want to do anything that threatens that.”

On Monday, though, Cooper reversed course:

"I have always been very open and honest about this part of my life with my friends, my family, and my colleagues. In a perfect world, I don't think it's anyone else's business, but I do think there is value in standing up and being counted. I’m not an activist, but I am a human being and I don't give that up by being a journalist."

Cooper also said that he ultimately decided that he was doing more harm than good by not speaking up:

"It’s become clear to me that by remaining silent on certain aspects of my personal life for so long, I have given some the mistaken impression that I am trying to hide something - something that makes me uncomfortable, ashamed or even afraid. This is distressing because it is simply not true. I’ve also been reminded recently that while as a society we are moving toward greater inclusion and equality for all people, the tide of history only advances when people make themselves fully visible."

Previously, the 45-year-old CNN anchor and daytime talk show host has been romantically linked to Benjamin Maisani, the co-owner of New York City gay bars Eastern Bloc and Bedlam.

Cooper becomes at least the sixth, though by far the most high-profile, openly gay anchor in the cable news business. He joins CNN colleagues Don Lemon and Jane Velez-Mitchell, as well as MSNBC's Thomas Roberts, Rachel Maddow and Steve Kornacki.

As Sullivan himself said in his post, Cooper is just the latest celebrity to come out in a relatively understated way. Just fifteen years ago, Ellen DeGeneres revealed she was gay in a storm of magazine covers and publicity. Now, though, stars are just as likely to quietly disclose their sexuality.

The statement prompted a flood of congratulations. Roberts, Lemon and DeGeneres all tweeted their well-wishes. So did Cooper's close friend Kelly Ripa. Gay rights group GLAAD also issued a statement.

"Even prior to coming out publically, Anderson's terrific work has raised awareness of inequalities facing LGBT people," GLAAD President Herndon Graddick said. "I'm proud to call him my friend. He's a role model to millions and now will inspire countless others."

  • Jim Parsons, 2012

    <em>New York Times </em>scribe Patrick Healy confirmed "The Big Bang Theory" star's sexuality<a href="http://www.nytimes.com/2012/05/27/theater/jim-parsons-prepares-for-his-lead-role-in-harvey.html?_r=1" target="_hplink"> as part of a profile</a>. The revelation came late in the article, when Healy describes the 39-year-old actor's role in the 2011 revival of Larry Kramer's HIV/AIDS crisis drama, "The Normal Heart." Wrote Healy: '"The Normal Heart" resonated with him on a few levels: Mr. Parsons is gay and in a 10-year relationship, and working with an ensemble again onstage was like nourishment, he said." Though the <em>Times </em>didn't identify Parsons' partner, he has been romantically liked with art director Todd Spiewak (pictured).

  • Anne Burrell, 2012

    "Secrets of a Restaurant Chef" host Anne Burrell confirmed she's a lesbian and in a committed relationship with a woman, just days after "Chopped" host Ted Allen made a reference to her sexuality in a radio interview. "Anne doesn't feel she was outed," Burrell's rep told Page Six. "She has made no secret of her relationship." The rep went on to note, "Her significant other is a very private woman. They have been together for a couple of years and spend a lot of time together."

The 43-year-old mother of three, who's long enjoyed a sizable lesbian fanbase, told <em>Out</em> that she first had a relationship with a woman while still in high school, after moving from her native England to suburban Michigan. "If I had thought I was 100 percent gay, would it have been a different experience for me?" Anderson, who was voted "Most Bizarre" and "Most Likely to Be Arrested" in high school, ponders. "Would it have been a bigger deal if shame had been attached to it and all those things that become huge life-altering issues for youngsters in that situation? It's possible that my attitude around it came, on some level, from knowing that I still liked boys."

It was my choice, too, because I was a bit worried about it but now I don't really give a shit. You can't hide away forever.
