Emma Watson is reportedly dating a 35-year-old tech wizard. The 'Harry Potter' actress has apparently found love with the handsome US Ivy League graduate William Knight, who is more commonly known as Mack and describes himself as a "tech and business entrepreneur". A source said: "Mack is just a normal, down-to-earth guy who has nothing to do with Hollywood, and Emma loves that." Emma, 25, previously dated rugby player Matthew Janney until their relationship ended in 2014. The split was devastating for the actress, but she and Mack has been dating for the last four months, during which time he visited Emma in her home town of Oxford for New Year. An insider told The Sun on Sunday newspaper: "She was left really hurt by her break-up 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." Emma revealed last year that she was so upset by her split from Matthew she took a week-long vow of silence at a retreat in Canada's Rocky Mountains. She said: "It was horrendous. I felt really uncomfortable. "Even before my relationship ended I went on a silent retreat, because I really wanted to figure out how to be at home with myself."
