Bradley Cooper and Renée Zellweger — along with Cooper’s actor pal Danny McBride — made a surprise appearance in the snow at the Sundance Film Festival this weekend to support Cooper’s pals Jonah Hill and his Hangover costar Justin Bartha, who both have movies showing at the fest.

Cooper, 35, and Zellweger, 40, arrived separately, and the couple has kept a relatively low profile since getting into town. Cooper flew solo Sunday and started off his morning with a quick trip to the USANA/Kari Feinstein Style Lounge. Saturday night also saw Cooper by himself hitting pal Hill’s Cyrus premiere at the Eccles Theatre. The casual twosome laughed throughout the night, and Hill, 26, thanked Cooper for coming. Bartha’s movie at Sundance is Holy Rollers.
