The Gay & Lesbian Alliance Against Defamation has announced its nominees for the 21st Annual GLAAD Media Awards, and Lady Gaga and Adam Lambert will face off in the race for Outstanding Music Artist. Other nominees for the awards include shows like "True Blood" and "Glee," as well as Robert Pattinson's flick "Little Ashes."

The awards seek to highlight shows, movies, music and other media platforms that provided "fair, accurate and inclusive representations of the lesbian, gay, bisexual and transgender community and the issues that affect their lives," according to GLAAD's Web site.

Gaga and Lambert are nominated against singer/songwriter Brandi Carlile, Gossip and Otep in the music category. Meanwhile, in the TV category, "Brothers & Sisters," "Grey's Anatomy," "Mad Men" and "Skins" are nominated alongside "True Blood" for Outstanding Drama Series. "Glee" finds its place in the comedy category alongside "Beautiful People," "Greek," "Modern Family" and "United States of Tara."

"Little Ashes" is nominated in the limited release category for film, while "Everybody's Fine," "I Love You, Man," "Precious: Based on the Novel 'Push' by Sapphire," "A Single Man" and "Taking Woodstock" make up the wide release category.

"Sex and the City" star Cynthia Nixon will be honored with the Vito Russo Award at the New York ceremony. She will receive the award for helping make "a significant difference in promoting equal rights for our community," the organization said.

"Cynthia Nixon has been a vocal and visible advocate who has transformed cultural attitudes about our community," GLAAD president Jarrett Barrios said in a statement. "She is a perfect example of how sharing your personal story and speaking out for marriage equality can inspire change among fair-minded Americans. It is our privilege to honor her."

The winners will be announced and honored at three ceremonies, at the New York Marriott Marquis on March 13, Los Angeles' Hyatt Regency Century Plaza on April 17 and San Francisco's Westin St. Francis on June 5.
