The Sundance Film Festival has been jam-packed with parties, red carpets, and star-studded events since it kicked off witha rip-roaring, blizzard-filled opening weekend. The Bing Bar played host to everyone from Drake on Saturday night to Kristen Bell for her House of Lies happy hour on Sunday. Elsewhere in Park City, Emma Roberts partied with her cast of Celeste and Jesse Forever, while Joshua Jackson caught up with his Lay the Favorite costars. LTF was getting a lot of buzz coming into the festival and was completed just days before it premiered.

Aziz Ansari took advantage of Sundance to schedule some stand-up, and he actually acted as Drake's opening act at the Bing Bar on Saturday. During the show, Cuba Gooding Jr. stormed the stage when he thought people weren't giving Aziz the attention he deserved. Aziz also stepped out to support his Parks and Recreation costar Rashida Jones, who made her screenwriting debut in Celeste and Jesse. Lizzy Caplan and Kirsten Dunst's movie Bachelorette hits Sundance on Monday evening, but the girls caught up beforehand as well. On Sunday, Lizzy joined Allison Brie, Christina Hendricks, and her husband Geoffrey Arend all sat together to enjoy a relaxing dinner at Chefdance. Bradley Cooper rolled into town late, since his film The Words is one of the last to premiere at the festival. There'still the final weekend and Sundance awards to come, but here's all the latest party pics from all the awesome events!

The foursome met up with a group on a mega yacht off the coast of St. Barts earlier this month, and they were spotted riding down a massive slide, swimming, and making a splash in the water. Elsa and Chris are expecting their first child together, and Elsa's baby bump was on display in tiny bikinis throughout the trip.
