Josh Groban

Sexy singer Josh Groban is dismissing rumors that he's dating pop star Katy Perry and is insisting they are just good friends. A host of Web sites reported earlier this week that the two musicians had become an item, with Perry's celebrity blogger friend Perez Hilton insisting the couple were trying to keep the romance under wraps. But Groban's representative Luke Burland has slammed the relationship rumors. He tells People.com, "Josh and Katy are very close friends and hang out, but they are not a couple."
