Celebrities were getting more and more into the holiday spirit this week and making sure to share their festive photos through social media. Jesse Tyler Ferguson and John Stamos both made visits to Santa Claus, while Lauren Conrad  reunited with her Laguna Beach costar Trey Phillips for a night of ice skating. Drew Barrymore  flaunted a fun polka-dot manicure, while Chrissy Teigen showed off a sleek new haircut, and Kim Kardashian  couldn't help but put her giant engagement ring on display while channeling her idol, Elizabeth Taylor. Meanwhile, Cameron Diaz  shared a photo of her new, self-confidence-boosting Body Book, while model Jessica Hart's body was in a bikini on the beach — and Beyoncé Knowles is also somewhere in this roundup, although she may be a bit difficult to spot at first glance.
