Actress Leah Remini has received an apology from former Scientologist Katie Holmes, which made her "want to cry".

The former King of Queens actress made headlines last week when she opened up about her very public exit from the Church of Scientology in 2013.

During the candid TV interview on 20/20, Remini detailed accusations allegedly made against her by Holmes and then-husband Tom Cruise after she attended their Italian wedding in 2006.

Remini claimed Holmes was among a number of Scientologists who filed complaints, known as "knowledge reports", about her alleged behaviour during the extravagant nuptials.

As a result she was chastised by organisation officials for "ruining" the wedding.

Holmes declined to be interviewed for the show, but she issued a statement apologising to Remini.

"I regret having upset Leah in the past, and wish her only the best in the future," the statement said.

In a follow up interview with Good Morning America, Remini said the statement almost made her "want to cry."

"It makes me emotional because at the time that Katie and this particular crew were writing reports it caused me a lot of time and pain," Remini said.

"I had no idea she was going through probably a lot more," she added.

Remini said she felt Holmes left Scientology to protect her daughter Suri.

"Now seeing her and Suri out there in the world and her being able to be with her daughter and live her life, you know, I'm touched by it."

Holmes has famously remained silent about her ex-husband Cruise and her time in the Church of Scientology ever since filing for divorce in 2012.

Remini is also set to release a tell-all book revealling Cruise is not all he's cracked up to be.

Once considered part of his inner circle, she claims to have witnessed shocking angry outbursts from the actor.

He reportedly lost his temper when an assistant handed him a chipped mug and lost it over cookie dough he thought was not properly prepared.
