An eyewitness gives HollywoodLife.com the scoop on Kirsten & Garrett’s Sundance party PDA!

Kirsten Dunst and Garrett Hedlund came up with a fun way to beat the Utah chill this past weekend — intense make-out sessions! The couple was spotted packing on the PDA at Sugar nightclub in Park City on Jan. 22, and an eyewitness tells HollywoodLife.com it’s obvious the couple is “so in love and not afraid to show it!”

This certainly goes along with our previous exclusive report that Kirsten has been gushing about the Tron: Legacy star to all of her friends.

She was overheard telling her girlfriends that “Garrett was ‘the one’ and she could see herself having kids with him” Jan. 12 at the Art of Elysium’s 5th Annual Heaven Gala in Los Angeles.
