Emma Watson 'loved up' with co-star

Emma Watson was spotted looking "very loved up" with her 'The Perks of Being a Wallflower' co-star Johnny Simmon in Los Angeles yesterday . 

The 21-year-old actress - who shot to fame playing Hermione Granger in the 'Harry Potter' films - reportedly fell for the 24-year-old actor on the set of the drama movie, which was shot in Pittsburgh, Pennsylvania, and they are still close after filming ended. 

A source - who spotted Johnny dropping Emma off at a restaurant where she was meeting friends - told US Weekly the pair "looked very loved up. Holding and hugging each other for a while and playfully kissing. [They] seemed very open and not trying to hide their affection". 

Although the relationship is relatively new, the pair are said to have become virtually inseparable 

A source said: "Emma and Johnny met shooting 'The Perks of Being a Wallflower' and have gotten serious fast. She loves how down to earth and normal he is and thinks he's the nicest guy. He feels the same way about her. She doesn't act like she's one of the biggest stars in the world." 

A second source added: "They have really fallen for one another and both aren't dating anyone else. She once said she'd never move to LA, but I think she's reconsidering, especially because Johnny lives in Los Angeles." 

Emma previously dated financier Jay Barrymore but their two-year relationship ended in March 2010 after two years.
