"Harry Potter" star Emma Watson is said to be utterly smitten with a new guy, a tech industry manager and marathon runner named William Knight, according to Britain's the Sun.

Knight — who is 10 years her senior and apparently goes by his middle name, Mack — is the first serious guy Watson has been linked to following her December 2014 split from Oxford University rugby player Matthew Janney.

"Mack is just a normal, down-to-earth guy who has nothing to do with Hollywood, and Emma loves that," a source says. "She was left really hurt by her breakup with Matthew, and it’s taken her more than a year to feel ready to start again with somebody. They’re really happy with each other and see each other whenever Emma does not have work commitments."

Part of that seeing each other reportedly included spending last week relaxing in Big Sur, California, at the swanky, $10,000-per-week Post Ranch Inn and sharing wood-fired pizzas at Big Sur Bakery. The California "normal" sounds pretty nice.
