Leah Remini gave "millions" to the Church of Scientology.

The 45-year-old actress left the church after 30 years in 2013 and admits during her time with the cult, she gave them a vast share of her fortune.

Asked by 'Watch What Happens Live' host Andy Cohen how much money she gave as a member, she replied: "Millions".

He then asked if it was over $3 million and she confirmed it was.

Despite her outspoken stance about the church and its members - most notably Tom Cruise, who she said had "an enormous amount of power" - Leah doesn't regret her time within the organisation.

She said: "Regrets? No, I'm here now. I wouldn't be here in this moment between these wonderful people. I'm happy that I'm here with experience."

It has previously been claimed Tom hasn't seen his nine-year-old daughter Suri for two years, and Leah believes that's because Scientology has ordered him to shun ex-wife Katie Holmes - who left the church when they divorced in 2012 - and so made it difficult to be around his daughter.

Andy said: "I'm fascinated by the Tom Cruise thing in terms of his daughter. If she allegedly left the church . . . If she's no longer a Scientologist, then does that mean he can't be in touch with her?"

Leah replied: "Well, she's a baby. She's a child. She doesn't have a choice. No, but the policy of the church is you can't be connected to someone who's committed a suppressive act, which I have. Katie has, per church policy. You can't be connected to that. You have to shun that particular person."

While she has a lot of criticism of Tom, the 'King of Queens' star had nothing but positive things to say about another famous Scientologist, John Travolta.

She said: "He's a very sweet man, and he loves the technology of Scientology. He's been lovely."
