London, Jan 21 (IANS) British actor Daniel Radcliffe is reportedly dating his "Kill Your Darlings" co-star Erin Darke.
The 23-year-old, who plays controversial gay poet Allen Ginsberg in the movie, was smitten with Darke but did not show it publicly until recently.
"Daniel was really taken with Erin on the set, but is cautious about coming out and saying he's seeing someone before he knows it's something special," thesun.co.uk quoted a source as saying.
"But he thinks now is the time to go public with the relationship," the source added.
Radcliffe was seen indulging in some public display of affection with Darke after the premiere of "Kill Your Darlings" at the Sundance Film Festival in Utah.
"They were getting very intimate at the party in a vodka lounge, kissing and with Daniel stroking her leg. He's usually not one for casual displays of affection so it obviously meant something," a source said.
The actor was in a relationship with production assistant Rosie Coker for two years before calling it quits in October last year.
