Julianne Hough 'not dating Ryan Seacrest'

Julianne Hough has reportedly laughed off reports suggesting that she is romancing Ryan Seacrest.

Speaking to OK, the Dancing With The Stars professional and country singer described speculation about her love life as "crazy".

"I keep hearing these rumours, but I don't know. I know him from interviews. We've had lunch together with people - my manager, and stuff like that," she said.

The star, who is not appearing in the current season of Dancing, added that she is supporting her brother Derek and his partner Nicole Scherzinger on the show: "They're really, really great. They have a lot of chemistry and they're great."

Hough can be seen opposite Cher and Christina Aguilera in the upcoming movie Burlesque.
