Daniel Radcliffe has a new girl. According to PEOPLE, the Harry Potter depicter was cozying up to his "Kill Your Darlings" co-star Erin Darke when attending Sundance Film Festival. They were spotted showing off PDAs at the Grey Goose Vodka Lounge dinner at the Blue Door.

"They were affectionate most of the night," a source told Us Weekly. Darke reportedly "was touching his knee" and sharing a brief kiss with him. "They were a little more obvious outside the venue after they were leaving." Outside later that night, he was draping his arm around her.

Although the two acted like an item and eyewitness confirmed it, the British actor played coy when asked about the nature of his relationship with the actress. "Erin? Oh, Erin Darke?" he told PEOPLE, dodging the question. "Yeah, the whole cast is here. It's fantastic."

They were joined at the event in Park City, Utah by some other big stars including "Dexter" leading man Michael C. Hall, who came with his novelist girlfriend Morgan Macgregor.
