Singer Adam Lambert will be honored at the 24th Annual GLAAD Media Awards set to take place Saturday, May 11 at the Hilton San Francisco – Union Square.

GLAAD announced Thursday that Lambert will received the group's Davidson/Valentini Award, which is presented to an openly LGBT media professional who has made a significant difference in promoting gay rights. The award is named after Craig Davidson, GLAAD's first executive director, and his partner Michael Valentini.

“Adam Lambert's continued success as one of the world's best-selling pop stars shows LGBT people that they can be themselves and make it in a mainstream industry that many feel unfairly rejects them,” GLAAD spokesman Wilson Cruz said in a statement. “Adam is fearless on stage and astonishes audiences in every country he performs in.”

Lambert last year helped pass a referendum in Maryland upholding a gay marriage law approved by lawmakers by headlining a fundraiser concert to benefit Marylanders for Marriage Equality. His sophomore album Trespassing debuted at Number One on Billboard's album chart, making him the first openly gay artist, and the seventh American Idol finalist, to reach the chart's top spot.
