Kirsten Dunst and Garrett Hedlund make out at Sundance Film Festival

Washington, Jan 26 (ANI): Kirsten Dunst has been dating Garrett Hedlund for months, but it was only in the Sundance Film Festival that they went public with their romance.

According to various eyewitnesses the 29-year-old was spotted kissing the Country Strong star at Monday's Bachelorette after party in Park City, Utah.

"Before leaving the party at 1:30 a.m., Kirsten and Garrett stopped to make out in the middle of the bar," the Us magazine quoted one onlooker as saying.

"He put his arm around her and then she pulled back and then they kissed again," the onlooker said.

"they were dancing to Sam Ronson's set and stayed on the dance floor most of the time," second eyewitness revealed.

When they weren't indulging in PDA, Dunst and Hedlund, 27, were chatting up fellow A-listers like Rashida Jones and James Marsden.

But a source insists that despite their affectionate outing, they are not expected to make any red carpet appearances in the near future.

"They have hung out and they hook up, but it's nothing serious," a source had said in December.

"They're having fun and keeping it simple and open. That's it," the source added. (ANI)
