Katie Holmes to Speak Out About Ex-Scientologist Leah Remini on Tonight's 20/20

US Weekly reports that Katie Holmes, ex-wife of actor and scientologist Tom Cruise, will speak out for the first time about ex-Scientologist Leah Remini on tonight's 20/20 on ABC News.

The actress, who divorced Cruise in June 2012 after almost six years of marriage, has never commented on the 'King of Queens' actress or anything else concerning Scientology. However, during his promotion of tonight's 20/20 interview with Remini on this morning's GMA, ABC News' Dan Harris told Robin Roberts and her co-hosts that the Dawson's Creek actress will make an appearance during the segment.

"You're also going to hear from Katie Holmes, the former wife of Tom Cruise," Harris teased. "[And] what she is now saying about Leah."
