The Gay and Lesbian Alliance Against Defamation says Madonna will present CNN's Anderson Cooper with an award for openly gay media professionals.
GLAAD told The Associated Press on March 2 that the singer was chosen to give Cooper the Vito Russo Award at the 24th annual GLAAD Media Awards in New York City on March 16.
GLAAD president Herndon Graddick said Madonna and Cooper are longtime friends who have both used their careers to support LGBT people.
Cooper declined to speak publicly about his sexual orientation for years.
But last July he gave blogger Andrew Sullivan permission to publish an email in which Cooper said he is gay and "couldn't be more happy."
Russo helped found GLAAD and wrote a book about gay people in the movies called "The Celluloid Closet," which has been adapted as a documentary.
GLAAD holds several media awards programs this spring, one in New York, one in Los Angeles and one in San Francisco.
