Rylan Clark-Neal played the long game after overhearing another celebrity "slagging him off".
The 33-year-old presenter has opened up about the time he heard a well-known star - who he hasn't named - insulted him during filming for 'Alan Carr's Chatty Man' in 2013.
He told The Sun newspaper's TV Biz column: "Shortly after 'The X Factor' I went on 'Chatty Man'. There was a guest on the show who is quite a famous actor in this country.
"I could hear him slagging me off, going, 'Why is that idiot on the show? He is an absolute this and that'. I let it go, but I always banked it."
A few years later, the pair bumped into each other at the National Television Awards and Rylan - who had since taken on hosting jobs on the likes of 'Big Brother' and 'This Morning' - found the perfect way to handle the situation.
He said: "In 2016 and 2017, I was up for the NTA and they asked me to present an award. I go backstage and see this guy walking towards me.
"He puts his hand out and says, 'Rylan, it is so nice to meet you. I am such a big fan. My daughters absolutely love you and they will kill me if I don't get a photo with you. Please can we have a photo together?'
"I had a little reality check and thought, 'I either punch him or do the decent thing for the daughters'. So I said, 'Yes, absolutely.' "
However, Rylan wasn't quite done as he waited until the perfect moment to remind the mystery star about his previous remarks.
He added: "As I walked away, I turned around and said, 'Mate, we have met before - on Chatty man, in 2013. Do you remember slagging me off?' "
