Daniel Radcliffe Girlfriend: Erin Darke?

Does Daniel Radcliffe have a new girlfriend? Yes, according to a very reliable source:

The actor's lips!

Witnesses tell People that the Harry Potter actor was spotted swapping serious spit with Your Darlings costar Erin Darke over the weekend, as they shared a smooch and a cuddle at the Sundance Film Festival.

The cozy incident took place at the Grey Goose Vodka Lounge dinner, which followed a screening of the film in which Radcliffe and Darke appear.

Young Darlings centers in a 1944 murder, with Radcliffe taking on the role of Allen Ginsberg.

"They've been dating for a while but have been debating going public," a source tells the magazine, while Radcliffe politely brushed of a question at the event about his "girlfriend."
