Christian Bale has asked for his privacy to be respected following assault allegations against him.

'The Dark Knight' actor - who is accused of "pushing and shoving" his mother Jenny and sister Sharon at his Dorchester Hotel suite in London on Sunday - wants to focus on promoting new movie 'The Dark Knight', rather than discuss his personal life.

"The Dark Knight" actor Christian Bale allegedly "pushed and shoved" his mother after being asked for $200,000 to help raise his sister's three daughters.

A legal source close to the case told Britain's The Sun newspaper: "Christian is a very wealthy young man and was asked to help his sister out financially."
