In an interview, Holmes responded to Remini's claims about meeting the 'Mission Impossible' star when he was in a relationship with Katie.

Remini reportedly made several comments about the incident and about Tom's place in the Church, TMZ reports.

In a 20/20 clip released, Leah said Tom and Katie were busy in some serious PDA during the visit, which provoked her to say, 'hey, get a room.'

According to a representative of Katie, they gave the following statement in the interview: 'I regret having upset Leah in the past and wish her only the best in the future.'
