Mariah Carey surprised a packed crowd at New York's Terminal 5 when she made an unannounced appearance at Out Magazine's annual Out 100 bash in honor of her director pal Lee Daniels.
The 43-year-old pop diva was introduced at the event by the stars of HBO's hotly-anticipated gay drama "Looking," and drew cheers from the audience when she emerged in a skintight evening gown, her face coyly hidden behind a fan, after a short delay.
"I'm a straight girl, so I don't really know why they asked me to be here -- but my boobs have been out for years," Carey quipped as she accepted the "Artist of the Year" award on Daniels' behalf. Of the "Precious" and "Butler" director, who is openly gay, she noted, "He's an innovator; he's a dear, true great person...I live for him."
The evening's other high points included live musical performances by Steve Grand and Debbie Harry, while the well-dressed crowd was also treated to an advance peek at "Looking," which stars out actors Jonathan Groff and Russell Tovey. Particularly moving was an appearance by Defense of Marriage Act (DOMA) plaintiff Edie Windsor, who received a Lifetime Achievement honor at the event.
Also spotted were honorees Laverne Cox and Lea DeLaria of "Orange is the New Black," newly out "30 Rock" actor Maulik Pancholy, "American Horror Story" star Denis O'Hare and celebrity blogger/entrepreneur Perez Hilton.
