Harry Potter Actress Emma Watson's Admirer

Actress Emma Watson, known for playing Hermione Granger in all the "Harry Potter" films, is having trouble with an obsessed fan. Sky News reported that the 16-year-old actress was recently approached by a man in his 20's who had been following her into her open lectures at her school in Britain.

"The man actually gate-crashed her school," the source said. "She was very alarmed and worried."

After the man began questioning Watson about the "Harry Potter" films, police arrived at the scene and questioned him.

While police warned the man to leave the actress alone, her school and parents began to take precautions to ensure her safety.

Watson, who now will have a bodyguard at the school, previously said that her increasing popularity has made having a boyfriend an impossibility.
