Celebrities didn't waste any time gearing up for all the Grammy Awards excitement. Throughout the past few days, stars have been stepping out for popular pre-Grammys parties in LA, giving us a preview of the faces we saw at Sunday's big show. Over at the MusiCares 2015 Person of the Year Gala on Friday, Lady Gaga chatted up former Vice President Al Gore and Tony Bennett, and Kat Dennings and Josh Groban gave us a glimpse of their romance. Meanwhile, a handful of celebrities saved their energy for daytime fun at the Roc Nation and Three Six Zero brunch on Saturday. While Beyoncé stole the spotlight with Jay Z and Willow Smith, Kim Kardashian caught up with Rihanna, and Nick Jonas and Demi Lovato inspired major flashbacks to their Disney days.

On Saturday night, Clive Davis's annual Pre-Grammy Gala and Salute to Industry Icons quickly became the place to be. Performances from the likes of Meghan Trainor, Sam Smith, John Legend, and Pharrell Williams got Taylor Swift busting some moves, and Miley Cyrus turned it into a date night with Patrick Schwarzenegger.
