Leah Remini was asked if Tom Cruise was a 'good person' while promoting the return of her A&E series 'Scientology and the Aftermath,' and the actress did not hold back.

'No! Just going to get straight to it, no! There is a public persona of the guy who looks at you directly in the eye and shakes your hand and hugs you and is an attentive person to you and there's the person behind the mask who is a completely different person,' answered Remini in a Reddit AMA.

'Someone could say we all have that - what we are to the public and who we are behind the scenes, but the people who are around Tom and work for Tom, not even people who are Scientologists, they will say he is diabolical.'

She then added: People who've worked with me will say I can be an a**hole - all actors can be. That is different. He's very similar to David Miscavige, they could be twins.'

Friends no more: Leah Remini was asked if Tom Cruise was a 'good person' during a Reddit AMA (Cruise and Remini in 2005)

No go: 'No! Just going to get straight to it, no!' said Remini, who also called Cruise 'diabolical'

Remini previously described the fallout with some major Hollywood players following her behavior at the wedding of Cruise and Katie Holmes in her book 'Troublemaker.'

After returning home from Italy, Remini writes in her book that she began to hear that Cruise's agent Kevin Huvane was upset about how she acted at the wedding, something she says that she completely understands.

'If my friend told me that someone had ruined his wedding, I would think she was a bitch too,' writes Remini.

And so Remini decided to call Huvane and apologize.

Remini writes that she said she was not making a scene, to which Huvane replied; 'So are you calling to apologize or are you calling to lie to me?'

She went on to apologize, telling Huvane; 'I am sorry that I upset you.'

Huvane responded by saying; 'You are probably one of the most classless people I have ever met.'

The conversation ended shortly after that. Huvane did not respond to a DailyMail.com request for comment.

Remini was criticized for, among other offenses, being late to the wedding and trying to switch her seat when she and friend Jennifer Lopez were put at different tables.

After her return, Remini was sent to Florida to be reprogrammed because of her behavior, something that she writes in the book cost her $300,000 and took the entire time of her hiatus away from her show King of Queens.

She was too embarrassed, however, to say why she was away, and therefore lied to her friends including co-star Kevin James and best bud Lopez - who had been her guest at the wedding.

When asked by James how her hiatus was she said 'great,' but writes that she was thinking to herself: 'I was in Florida getting my a** handed to me for changing a f***ing seat.'

With Lopez, Remini said she made the whole thing sound like 'a casual trip to Disney with [her daughter] Sofia.'

Remini writes: 'Being a Scientologist was like having a double life.'

Remini also revealed in the book that she feared she would lose her family after renouncing Scientology.

The 45-year-old says she worried that her husband Angelo Pagan and her mother Vicki Marshall would not speak to her after she left the religious group, in a new interview with People.

But the actress was proven wrong as both Pagan and Marshall followed her out of the Church in 2013.

'They simply put family ahead of the Church, which is oftentimes not the case with Scientology families,' the King Of Queens star said.

'I've been given a second chance,' she added.

Remini was raised in the religion by her mother since the age of eight and only in her early forties did she decide to leave.

Prior to becoming an apostate, the actress was a dedicated member and as a teenager even spent a year in the Church's elite Sea Org headquarters in Clearwater, Florida, performing manual labor.

Since renouncing the religious movement, Remini has been outspoken in her criticism of the Church (Scientology has denied all allegations made by the actress).

In the book she also offers an inside glimpse of Cruise and other celebrity Scientologists.

It is not all negative either, as Remini appeared on Howard Stern in 2015 and spoke about how much she loves John Travolta, who she called a 'sweetheart.'

Meanwhile, Remini recently fought back tears during an emotional interview with ABC News that same year while talking about her decision to leave Scientology - and how she now understands why Katie Holmes also left the Church.

Remini told Amy Robach that she did not want her 11-year-old daughter Sofia to have to choose between her family and the Church, a decision she believes that Holmes also made for her daughter Suri.

'I know now she did what she did because she had to protect her daughter, which in a way connects us,' Remini said of Holmes.

She then said of Sofia: 'I didn't want my daughter to choose the Church.'

Remini, 45, also detailed the 'fighting' that went on between her and Holmes after the actress wrote a knowledge report about Remini following her 2006 wedding to Cruise.

'I was dismayed at the behavior of Leah Remini during the events leading up to our wedding,' Holmes allegedly wrote in a knowledge report that Remini read during an interview with 20/20.

'At the wedding, the behavior as a guest, a friend... was very upsetting.'

Holmes released a statement on Friday saying: 'I regret having upset Leah in the past and wish her only the best in the future.'

Remini got choked up while Robach read Holmes' statement to her, saying: 'At the time I was fighting with her - I guess for the lack of a better word - within the Church and now I know really what she was going through because at the time I was thinking of myself and my family and what we were going through.'

She then added: 'I had no idea she was going through probably a lot more.'

Holmes and Cruise split in 2012 and the actress and her daughter both left the Church.

Remini also called Scientology an 'extremist religion' in her interview to promote her autobiography Troublemaker, which will be released this week.

Despite her criticism of people within the Church however, Remini said that Scientology did help her in many ways growing up, and gave her confidence.
