Watson linked to co-star Simmon

Emma Watson is reportedly dating her 'The Perks of Being a Wallflower' co-star Johnny Simmon.

The 21-year-old actress - who shot to fame playing Hermione Granger in the 'Harry Potter' films - is said to have fallen for the 24-year-old actor on the set of the drama movie, which is being shot in Pittsburgh, Pennsylvania, and the pair are already very close.
