Pink, Ricky Martin and Bette Midler were among the stars who attended Saturday night's fundraiser benefiting the Human Rights Campaign (HRC), the nation's largest gay rights advocate.

According to gay glossy The Advocate, Martin welcomed guests as they arrived at the group's 14th annual National Dinner at the Walter E. Washington Convention Center in D.C.

“This is very simple. It took me a while but tonight I'm here and I want to say that I want to add my voice to yours. And I'm so happy to be part of this community,” Martin told the crowd, referring to his recent coming out gay in March.

“It was an amazing night!” he later tweeted in Spanish and English to his nearly 2 million followers.

Martin's inclusion in the fundraiser was not previously publicized.

Openly bisexual, Grammy-winning Pink was presented with the group's Ally for Equality Award, while actress-singer Better Midler served as a presenter.

Pink announced last week that the video for the just-released single Raise Your Glass will be set at a gay wedding.
