Ricky Martin, Adam Lambert, Frank Ocean, Chely Wright and Jay-Z are among the celebrities on Billboard's 25 Great Gay Moments In Music list.

According to Billboard, these 25 musical moments have been pivotal in advancing LGBT understanding, acceptance and rights.

On the brink of releasing his debut solo album, Channel Orange, R&B artist Frank Ocean revealed last year that his first love was another man. Ocean's confession didn't get in the way of Channel Orange racking up major accolades.

Adam Lambert publicly came out gay on the cover of Rolling Stone following his 2009 second place finish on American Idol. His star since has only risen higher.

Ricky Martin came out gay in his 2010 autobiography Me after ducking rumors about his sexuality for years. He's since released a new album, starred in a Broadway musical and is a current judge on the Australian version of The Voice.

Jay-Z was among the celebrities who last year voiced support for gay marriage: “What people do in their own homes is their business and you can choose to love whoever you love. That's their business. It's no different than discriminating against blacks. It's discrimination, plain and simple.”

Country music singer Chely Wright came out gay in her 2010 memoir Like Me. Her coming out experience was the subject of the award-winning documentary Wish Me Away. Last year, she married wife Lauren Blitzer, and together they celebrated the birth of their twin boys on May 18.
