Pop quiz: Who loves Christmas more, Mariah Carey or Rihanna? Both female singers put their affection for the holiday season on display via Instagram, where everything from gift wrapping sessions to after hours meetings with Santa Claus was documented.

Mimi hit the slopes in Aspen, Colo. with husband Nicki Cannon and twins Monroe and Moroccan, while RiRi spent the week in her home of Barbados–making us feel jealous of those glorious 80-degree temps with every post. They weren’t the only ones enjoying some holiday cheer and/or well-deserved R&R: Taylor Swift and Jessica Alba revealed a shared love of holiday pajamas, and Bar Refaeli reminded us that time away from the office is no excuse to slack on our beauty regimen (even if we get queasy at the sight of blood). You may have been busy hopping from multiplex to Netflix in an effort to catch up on some of the best movies of the year, but the BBC reminded fans that their beloved Sherlock returns in just a matter of hours. That means you + Benedict Cumberbatch SO SOON.

From engagement rings to tiny bikinis and festive onesies, see what your favorite stars gave and received this year, as well as how they celebrated the holiday in our weekly ’gram rewind.
