Katie Holmes' former fiance Chris Klein fears the actress is being brainwashed by Tom Cruise's Church Of Scientology.

The Batman BEGINS actress has converted to the religion at the request of her new fiance - but Klein, who split from Holmes shortly before she began dating Cruise, fears she is not being allowed to make her own decisions.

He says, "A lot has been made of her getting into Scientology.

"I hope that she's making decisions that are making her happy and that she doesn't have people in her life leading her astray from what she wants and what she believes."
