According to TMZ, Ashleigh Johnson attended a free Jo Bros concert at Los Angeles' The Grove in May 2010, during which the overzealous crowd pushed her into a guard rail. Johnson claims she was "agonizingly crushed," which resulted in serious mental, emotional and physical injuries.

The lawsuit targets the performers' corporate entity, Jonas Brothers Enterprises, as well as Caruso Management, the company that runs The Grove.
