Taylor attended and emceed the 2012 Grammy nominations concert, where in addition to beat-boxing with LL Cool J, she also celebrated her three nods. Now, though, Taylor's attention is back on her One Direction boyfriend. Yesterday, Taylor and Harry showed PDA at a friend's birthday bash held at the Crosby Street Hotel. Other celebs turned out for the fun too, including Emma Stone and Dianna Agron. Their evening out came after a romantic weekend, during which Taylor and Harry had a fun, and much-photographed, adventure to the Central Park Zoo.
