Katie, who is married to Tom Cruise – who we all know is a Scientologist, was engaged to Chris from 2003-2005.
She wants to help Chris, who may face up to a year in prison for drink-driving.
‘Katie is a devout member and she believes deeply in their addiction program, Narconon, and its power to change lives,’ a source told Star magazine.
‘She has been reaching out to Chris and encouraging him to seek help there. She really believes it’s the best thing for Chris’
