Stars got a head start on the Grammys celebrations with a special event honoring Bruce Springsteen in LA last night. The MusiCares Person of the Year gala brought out Katy Perry, who is nominated and will present at Sunday's Grammys, as well as Chrissy Teigen and John Legend. John performed after returning to the West Coast with Chrissy from a visit to NYC, where they attended the amfAR Gala. Faith Hill and Tim McGraw walked the carpet and also took the stage together, and Marcus Mumford hung out backstage with Johnny Depp after singing with Mumford and Sons. Bruce, the man of the hour, rocked the crowd with a performance himself, while Elton John, Sting, and others looked on. There's more Grammys fun to come before the big show — make sure to watch right here on POPSUGAR live Sunday at 4:30 p.m. EST/1:30 p.m. PST for all the action!
