The 27th Annual GLAAD Media Awards honored Mariah Carey, Robert De Niro and the best in LGBT media in New York City on Saturday. Laverne Cox hosted the festivities.

Jennifer Lawrence gave a surprise appearance when she presented Robert De Niro with the Excellence in Media Award for his HBO documentary “Remembering the Artist: Robert De Niro Sr.” The documentary focused on De Niro Sr.’s struggle to hide his sexuality before coming out later in life.

“Robert De Niro Sr. was a gay man who struggled with self-acceptance at a time when organizations like GLAAD were not around,” Lawrence told the audience in the Waldorf Astoria.

“Around the time this film premiered, Bob said something that really resonated with me. He voiced the hope that this documentary would allow his children to fully understand the urgency of the present,” Lawrence continued. “He said, ‘I want them to stop and take a moment and realize that you sometimes have to do things now, instead of later, because later may be twenty years from now and that’s too late.'”

Director Lee Daniels presented Mariah Carey with the Ally Award. Carey told the crowd she wanted to understand what “LGBTQ” stands for before attending the award show.

“I had to learn a whole new alphabet to introduce and not un-include people,” Carey said. “I don’t want to do it wrong. I decided that if I have to memorize it, I might as well elaborate on it. So we have L: legendary. G: gorgeous. B: beautiful — all of you beautiful people. T: tantalizing, and even Q for quality.”

“Thank you for the unconditional love. I thank you, and I wish all of you love, peace and harmony,” Carey continued.

Comedian Aziz Ansari also honored “Anderson Cooper 360” for its segment on U.S. Supreme Court plaintiff Jim Obergefell.

Other winners included Caitlyn Jenner and Diane Sawyer’s “Bruce Jenner: The Interview” on “20/20” for Outstanding TV Journalism – Newsmagazine, “Tangerine” for  Outstanding Film – Limited Release and Cosmopolitan for Outstanding Magazine Overall Coverage.
