Music's biggest night opened up with a bang as power couple Beyonce and Jay Z took to the stage with a show-stopping performance.
They're fresh off a 22-day vegan cleanse and it shows. Beyonce, sporting a new bob, is in incredible shape and she highlighted her fit figure in a black thong bodysuit. The headlines are calling the performance "steamy" and "naughty!"
Jay Z dedicated his win for Best Rap Song Collaboration to their daughter, Blue Ivy, saying, "I want to tell Blue that, 'Look, Daddy's got a new gold sippy cup for you.' "
Pink wowed the A-list crowd with aerial acrobatics, performing while dangling over the crowd in Cirque du Soleil fashion. Did it look familar? Pink also went up, up and away at the 2010 Grammys, but her daring spins at this year's show were even more thrilling.
Taylor Swift took center stage, whipping her flowing locks in an emotional performance of "All Too Well," said to be about ex-boyfriend Jake Gyllenhaal. Taylor's parents joined the standing ovation for their daughter.
Taylor had an oops moment when she thought she had won Best Album of the Year. She made a quick recovery when she realized the real winner was Daft Punk.
The robots got lucky all night long, winning Album and Record of the Year. So who are the men behind the masks? They're a pair of French musicians who never perform without their helmets.
Another big Grammy moment went to Pharrell Williams and his bizarre, oversized fedora. It became an instant internet sensation and now has its own Twitter handle with 16,000 followers.
Fast food chain Arby's noticed a resemblance to the hat in their logo, tweeting: "Hey Pharrell, can we have our hat back?"
But Pharrell got the last laugh, replying to the sandwich chain: "Y'all tryna start a roast beef?"
