half mastRumors are swirling about a possible romance between country beauty Julianne Hough and comedian/actor Dane Cook. Over the weekend, the two were spotted sitting side by side in a private dining room at a Hollywood sushi restaurant, just before Julianne watched Dane perform at the legendary Laugh Factory. According to PEOPLE, a source saw the two kiss as they exited the club together.

On Wednesday (Mar. 3), Julianne and Dane were spotted again together -- this time leaving a West Hollywood hotel, laughing, as the singer walked to her waiting car. She Tweeted that afternoon that she was headed to the Los Angeles airport to fly back home to Nashville.

According to PEOPLE, reps for both Dane and Julianne had no comment on the speculated relationship between the two stars.

Neither Julianne nor Dane are strangers to tabloid fodder about their love lives. A few years ago, Dane was linked to Jessica Simpson, just after her divorce from Nick Lachey. Julianne was splashed all over the gossip headlines last year when she was spotted out with Kings of Leon bassist Jared Followill, soon after her split from fellow country singer Chuck Wicks.
