According to ex-Scientologist Leah Remini, Holmes isn't allowed to eat with Remini because it could see Holmes lose custody of Suri — claims denied by the church.
"We used to be close friends," Remini told LaPalme magazine. "It's quite sick, really."
Holmes and Cruise became engaged in 2005 after a quick and at times bizarre public romance.
During a now infamous appearance on The Oprah Winfrey Show, Cruise jumped on the talk show host's sofa to declare his feelings for Holmes.
"I'm in love! I'm in love," Cruise yelled while fist pumping the air. "I can't be cool. I can't be laid-back. It's something that has happened, and I feel I want to celebrate it. I want to celebrate her. She's a very special woman."
The couple welcomed daughter Suri in April 2006, tying the knot in a lavish Italian ceremony later that year attended by the likes of Victoria and David Beckham.
Cruise was previously married to Nicole Kidman from 1990 to 2001, the couple adopting two children together; Isabella, now 25, and Connor, now 23.
Prior to that Cruise was wed to Mimi Rogers from 1987 to 1990.
Since splitting from Cruise, Holmes is now dating actor Jamie Foxx, the couple going public with their relationship in 2017 after years of speculation.
