The actor was joined by his sister Julie Pruski and both were clearly choked up as Caputo proved she was in contact with their dead mum and dad by listing details about their wedding anniversary and deaths.

Parsons tells U.S. new show Entertainment Tonight, "It was very intense and very moving.

"She's the right medium, I guess you could say, to get across some deep messages. I just love her."

Actresses Susan Lucci and Jamie-Lynn Sigler also sat down for a reading with Caputo, as part of a celebrity special, which will air in America on 3 January (16).
