Is Katherine Heigl Religious?

My guess would be no, since she smokes, drinks and swears.

Heigl worships herself

I don't think so but she has expressed a desire to be more active in the Church.

Better than worshipping some imaginary all powerful invisible friend.

Narcissism is better than theism, certainly.

Yes she is

I believe she is since she did a few hallmark channel movies.

Religion and Hollywood are like fire and water...
BTW, to her!
