She's a regular at the annual Park City cinema celebration, and Kate Bosworth was back for another go-round as she was spotted taking part in the 2012 Sundance Film Festival happenings on Saturday afternoon (January 21).

Among the day's doings, the 29-year-old actress hit up the Getty Images Portrait Studio at T-Mobile Village at the Lift to tend to a portrait session alongside her "Black Rock" castmates.

Striking a range of poses, Kate stood alongside Lake Bell and pregnant director/co-star Katie Aselton before the trio of gals were joined by Jay Paulson, Will Bouvier and Anslem Richardson.

Also on the docket, Miss Bosworth stopped by the Puma Social Lounge at T-Mobile Google Music Village where she signed a few autographs and mingled with fellow guests such as James Marsden and Frank Langella.
