Mika, Anderson Cooper, Frank Ocean and Kristy McNichol were among the celebrities who came out gay in 2012.

British singer-songwriter Mika spoke about his relationship for the first time in the September issue of Instinct: “If you ask me am I gay, I say yeah. Are these songs about my relationship with a man? I say yeah. And it's only through my music that I've found the strength to come to terms with my sexuality beyond the context of just my lyrics. This is my real life,” Mika said.

After years dodging rumors, CNN anchor and daytime talk show host Anderson Cooper announced he's gay in an open letter to The Daily Beast.

“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,” Cooper wrote.

Frank Ocean, who snagged six Grammy nominations this year, is credited as the first mainstream hip-hop artist to come out bisexual.

Actress Kristy McNichol told People.com that she has been in a 20-year relationship with her partner Martie Allen.

Also coming out this year were actors Jim Parsons, Joanna Johnson and Matt Bomer. Sam Champion, the GMA weather anchor, also came out, as did Olympian Megan Rapinoe.
