Musicians, actors, and industry bigwigs flooded LA's Staples Center last night for the 52nd installment of the Grammy Awards. Beyonce and Taylor Swift, nominated for a combined 16 statues, swept the night, while Lady Gaga, who rocked two separate silver numbers (and a stage costume) only managed to pick up the Best Electronic Dance Album award. Other attendees ranged from Ringo Starr and Stevie Nicks to the cast of MTV's Jersey Shore.
