The former POTUS says that he handed over a cassette of Sir Elton John's 'Rocket Man' and 'a player to Mike Pompeo (former US Secretary of State) so he could play the song for the North Korean leader.
To give things context, at the time, denuclearisation talks were going on and Trump felt it was appropriate for a bit of trolling.
Well, the American billionaire was talking about his antics at a 'History Tour' in Florida on Saturday (11 Dec), reports Daily Star.
However, speaking at the event, Trump claims that the leader was not impressed by the gesture.
When asked if he knew the song, Kim Jong-un apparently responded, 'no'.
Trump said: "I made sure the machine wasn't made in South Korea. I played it for him quickly and I said: 'I did you a great favour because you love sending rockets all over the place'."
He went on to say how he 'envisioned' Kim Jong-un sitting on a 'rocket flying over Japan'.
The dictator was nicknamed 'Rocket Man' by Trump in 2017 after referring to him in a tweet.
It read: "I spoke with President Moon of South Korea last night.
"Asked him how Rocket Man is doing. Long gas lines forming in North Korea. Too bad!"
Trump is set to continue his tour on December 18 and 19 at the Toyota Centre in Houston and the American Airlines Centre in Dallas.
Earlier this month (1 Dec), Trump lashed out against Meghan Markle during an interview with Nigel Farage.
Speaking on the GB News channel, the former US President, who has never been fond of the Duchess of Sussex, didn't hide his discontent for her.
'I'm not a fan of hers," he remarked to the former UKIP leader. "I wasn't from day one. I think Harry has been used horribly and I think some day he will regret it.
"I think Harry's been used and been used terribly. I think it's ruined his relationship with his family, and it hurts the Queen," Trump said on GB News.
"I think [the Duchess of Sussex has] been very disrespectful to the Queen, who's such a great woman, such a great person, a historic person.
"I think she's very disrespectful to the Royal Family and most importantly to the Queen."Featured Image Credit: Alamy
