Daniel Radcliffe was reportedly cosying up to his co-star Erin Darke in the frigid cold of Park City, Utah.
The British actor and his fellow Kill Your Darlings star are rumoured to be involved in a burgeoning romance.
The pair are in Utah at the Sundance Film Festival promoting their movie about how murder united beat generations authors Allen Ginsberg, Jack Kerouac and William Burroughs.
Daniel and Erin seemed to be enamoured with each other while sitting at their VIP table at Grey Goose Blue Door Friday.
"They were affectionate most of the night, [Erin] was touching his knee," a source told Us Weekly magazine.
"They were a little more obvious outside the venue after they were leaving."
Apparently the pair have "been seeing each other" covertly for a while in New York City, where they both currently strike up residence.
A source revealed to the publication that Daniel and Erin are on the fence about whether or not to go public with their romance.
Daniel has previously dated actress Laura O'Toole and production assistant Rosie Coker.
