Plenty of people got really excited when the 25-year-old Harry Potter star was photographed having lunch with a handsome man in Los Feliz, California this past Sunday, but a source tells ET the pair are actually just longtime friends.
The mystery man is 27-year-old actor/producer Roberto Aguire, whom Watson met on the set of 2005's Harry Potter and the Goblet of Fire when he was an intern.
And the story of how they met couldn't be more adorable. "They started dancing together in a hallway and that’s what sparked the friendship," the source says.
The two also clearly have a few things in common. Much like Watson, who graduated from Brown University last May, education is also obviously important to Aguire -- he speaks five different languages and graduated from New York University.
In August, Watson opened up about her painful breakup with her ex-boyfriend, British rugby player Matthew Janney. The two split in December.
"I felt really uncomfortable, even before my relationship ended," she told Vogue UK. "I went on a silent retreat, because I really wanted to figure out how to be at home with myself."
"The boyfriends or partners I've had have generally made me feel really cherished," she added. "They've built me up. I certainly haven't found that with doing all that I do or being all that I am, that I've struggled in my love life.”
