Madonna was a surprise attendee at the premiere of '12 Years a Slave' on Tuesday, Oct. 8. Inside the screening at Lincoln Center's Walter Reade Theatre, however, the pop legend apparently dispensed with standard moviegoer etiquette. As first reported in the New York Post's Page Six, "a mysterious blonde in black lace gloves who wouldn't stop texting throughout the first half of the movie" sat in front of one anonymous audience member. The irked moviegoer continued: "Eventually, a woman next to me tapped her on the shoulder and told her to put her phone away, and the blonde hissed back, 'It's for business... enslaver!'" The observer eventually figured out that the rude, unapologetic lady in black gloves was Madonna herself. Another attendee at the screening tells Us Weekly: "Some people are shocked by this, because Madonna was visibly tearing up, everybody there thought that she was very moved by it. She really wanted to say hello to Steve McQueen and congratulate him."
