Emma Watson has been single since her “horrendous” December 2014 breakup with Matt Janney but after she was seen with a hunky new guy, that might not be true any longer.

The mystery man is Roberto Aguire whom she met on the set of Harry Potter and the Goblet of Fire.

Emma Watson and Roberto Aguire went out for a casual lunch in Los Feliz, California, on October 4, where they looked completely comfortable and happy with each other.

The 25-year-old actress sported an oversized white blouse and long denim skirt while Roberto rocked a pair of black thick-framed glasses, a baseball cap, a T-shirt and a pair of lace-up sneakers. This was definitely a casual affair.

This is the first time Emma is spotted with a potential new love since she broke up with former boyfriend Matt Janney.

Emma Watson first sparked rumors of a romance with Janney, a University of Cambridge player, after they were spotted hugging and kissing in the Caribbean.

Opening up in an interview with Vogue Magazine, Emma Watson admitted that her split from Matt Janney was so 'horrendous' that she had to take some time to feel 'at home with herself' again.

The 25-year-old revealed how she travelled to a silent retreat in Canada's Rocky Mountains to help come to terms with the breakdown of the relationship.

"I felt really uncomfortable," she said in an interview with Vogue U.K. "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."

Emma Watson and Oxford rugby star Matthew split at the end of 2014 after a year of dating. A spokesperson confirmed the break-up was down to the actress' "unrelenting work schedule", adding that things remained "amicable" between the pair.

Prior to that, Emma was in a long-term romance with fellow Oxford student Will Adamowicz – they dated from 2011 until early 2014.
