Anne Hathaway performed a lively singing tribute to Meryl Streep during the broadcast of the Kennedy Center Honors last night—and she broke out a split! While melodically belting out lyrics like "She's My Pal" to her Devil Wears Prada co-star, the newly-engaged actress dropped down to the ground in a full-on split, begging the question, What gown could allow such flexibility? We have the answer! The white and black lace design is from Oscar de la Renta’s spring 2012 collection. She topped it off with Fred Leighton jewelry, including a coral, onyx and diamond bracelet and diamond stud earrings. What a high-fashion look for an on-stage gymnastics move!
