Robert Pattinson is desperate to return home to London because he's sick of obsessive female fans hassling him in New York.

The Twilight star is currently filming his new movie, "Remember Me," in the Big Apple, and was recently struck by a taxi while trying to escape a group of over-excited devotees.

Pattinson has reportedly become so annoyed with the behavior of girls on the streets of Manhattan, he has started pining for his native Britain.

A source tells the New York Daily News, "Robert is dying to get back home. He's so over everything. He's overwhelmed by all the girls - they terrify him! He says girls grab his neck and clothing all of the time, and he's not used to that. Fans don't do that to him in London. Everyone there is a little cooler about the fame thing, which is what he's used to."

And the heartthrob actor is so unhappy with life in America, even his co-stars are concerned about him.

The source adds, "He's so skinny and stressed. Everyone on set is worried about him... Robert doesn't understand why everyone is going so crazy over him. He's embarrassed by the way girls throw themselves at him. The girls here are stalking him. He stayed in two different hotels over the course of four days just to try to escape the fans who were following him. He's afraid that if he gives a hand, they'll take the whole arm. He's being advised by security not to encourage the crowd, so he doesn't even look up anymore."

Pattinson's "Twilight" co-star Michael Welch spoke out last month about his pal's fanatical admirers, saying, "Is it time to start getting concerned here? It's tough, man... I don't know where his life is really headed."
