Jonas Brothers Fan Sues -- They Have a Huge Crush On Me

A Jonas Brothers fan has sued the group, claiming they're so popular, she was crushed during a concert by crazed groupies.

Ashleigh Johnson filed the lawsuit -- obtained by TMZ -- in which she claims she was at The Grove in L.A. back in May, 2010, watching the boys perform an early bird special (3 PM), when she was pushed by an uncontrolled crowd against a guard fence.

Ashleigh says she was "agonizingly crushed" into the fence and suffered serious mental, emotional and physical injuries as a result.

Ashleigh -- who didn't ante up her age -- is suing the group as well as Caruso Management, the folks behind The Grove.
