Ryan Seacrest and Julianne Hough can no longer act so coy — they’ve been spotted kissing on Seacrest’s yacht while on a romantic vacation in Portofino, Italy. Sources said a set of sensational photos now making the rounds show dancer/country singer Hough wrapping her legs around the “American Idol” host as she greets him onboard after jetting in from Atlanta. The lovebirds are now believed to have set sail for Monaco. Although Page Six first reported they were dating two months ago, both have refused to confirm they’re an item. A rep for Seacrest didn’t get back to us.
