Or is it just the media making stuff up again?

Friends say the singer has asked Tom and Katie for advice
by Jen Crothers
Britney has dabbled with religion before (Kabbalah, anyone?), but now she's looking into Scientology to solve her woes - with the help of famous followers Tom Cruise and Katie Holmes.
Britney told a friend, "I have met Katie a few times, so I called her up and just started asking questions about Scientology. I'm always open to new things. Katie told me she wasn't so sure about it at first either, but once Tom explained it to her and she read the books and took some classes, it really started to work for her. Then Tom wanted to talk to me about it, so I did. He was nice and answered all my questions and sent me books."
