"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."

Maggie Gyllenhaal says being on the red carpet is "unbearable." The 30-year-old actress - who wore a revealing backless black jumpsuit to the European premiere of 'The Dark Knight' - has had to learn to ignore people's catty comments about her clothes.

Speaking about her premiere preparations, Maggie - who plays leading lady Rachel Dawes in the film - told BANG Showbiz: "To be honest it takes a while to get ready and a lot of thought. But the amount of scrutiny is sometimes unbearable.

In the midst of "The Dark Knight" breaking movie records, Batman's Christian Bale was arrested in London Tuesday. The arrest is a result of assault allegations reportedly made by his own mother and sister.

Bale, 34, allegedly lashed out at his mother Jenny, 61, and sister Sharon, 40, on Sunday at London's Dorchester hotel. The actor was staying at the hotel before Monday's London premiere of "The Dark Knight." According to Britain's The Sun newspaper, Bale's mother and sister went to a police station in Hampshire Monday, which turned the case over to London officers. "A 34-year-old man attended a central London police station this morning, by appointment, and was arrested in connection with an allegation of assault," a police spokesman told People.com "He is currently in custody." It is a policy in England to arrest a suspect before questioning him in connection to a possible crime. Bale has not been formally charged, therefore the police did not release his name.
