This year's GLAAD Media Awards to be the most glamourous ever

Openly gay recording artist Adam Lambert will perform at the 21st Annual GLAAD Media Awards Presented in Los Angeles by ABSOLUT® Vodka on April 17, at the Hyatt Regency Century Plaza.

The GLAAD Media Awards elevate and promote fair, accurate and inclusive stories of lesbian, gay, bisexual and transgender (LGBT) issues, people and allies that have increased awareness, understanding and respect for the lives of LGBT people. The GLAAD Media Awards also fund GLAAD's work to amplify stories of LGBT people and issues that build support for equality.

Lambert's debut album, 'For Your Entertainment', debuted at #3 on the Billboard 200 and has since been certified Gold by the Recording Industry Association of America. He is nominated this year for a GLAAD Media Award for Outstanding Music Artist.

"GLAAD has advocated for out music artists, including myself, and I am proud to be part of the 21st Annual GLAAD Media Awards this year," said Adam Lambert. "GLAAD's work to share stories that grow acceptance and understanding about the gay and transgender community is so important in our culture today."

GLAAD also confirmed that Constance McMillen, the 18-year-old student from Fulton, Mississippi whose high school cancelled a prom rather than permit McMillen to attend with her girlfriend, would be presenting Wanda Sykes with the Stephen F. Kolzak Award. With the help of the American Civil Liberties Union, McMillen filed suit against her school, asking them to reinstate the prom for everyone, without discrimination. This week, a federal judge in Mississippi ruled that while he wouldn't force the school to hold a prom but agreed that McMillen's First Amendment rights had been violated.

Golden Globe-winning actress Drew Barrymore will be honored with the Vanguard Award at the Los Angeles ceremony.

Candis Cayne and Wilson Cruz will host the event. Other guests and presenters scheduled to attend include cast members from Glee, Tom Ford ('A Single Man'), Eric Dane ('Valentine's Day', 'Grey's Anatomy'), Jason Lewis ('Sex & the City'), Sofia Vergara ('Modern Family'), Chaz Bono, Benjamin Bratt ('La Mission'), RuPaul ('RuPaul's Drag Race'), Bryan Batt ('Mad Men'), Rob Halford of Judas Priest, Elizabeth Keener, Clementine Ford ('The L Word') and Countess LuAnn de Lesseps ('Real Housewives of New York City').
