No dress code to worry about here! Beyonce, who seemingly abided by CBS' widely flouted ban on skimpy looks the Grammys in L.A. Sunday -- got super-duper sexy again at the premiere of her HBO documentary Life Is But a Dream in NYC on Tuesday (Feb. 12).
The "Love on Top" singer, 31, flashed her cleavage in a greige embellished gown with fine floral applique (and very strategic cutout) from the Elie Saab Spring 2012 Haute Couture collection. Introducing pal Justin Timberlake's much-anticipated Grammys performance on Sunday, Beyonce (with Ellen DeGeneres by her side) stayed covered up in a black-and-white Osman Studio jumpsuit -- and pants!
At Tuesday's premiere (with the screening held at the Ziegfeld Theater and afterparty at Christie's auction house), Beyonce's most boldfaced fan in attendance was Oprah Winfrey, who interviewed her onstage for about 10 minutes before the screening.
Winfrey, 59, frequently called Beyonce the "beloved mistress of the world" during the exchange and unearthed the inspiration behind the film's title: It's a refrain from "Row, Row, Row Your Boat," which is 13-month-old daughter Blue Ivy's favorite song.
