Vladimir Putin tested Conor McGregor's whiskey for poison when the pair met.
The Dubliner claims he gave the “very first bottle” of Proper Twelve Irish Whiskey to the Russian President in 2018.
But Putin's security confiscated the bottle of booze to check it for poison, according to McGregor.
Speaking at a press conference in Moscow back in 2019, the UFC star said: "Many people don't know, the very first bottle of Proper Twelve Irish whiskey, I gifted to Vladimir Putin.
"President Putin's security detail is second to none as I'm sure you know, you don't mess around with Vladimir.
"So, I gifted the bottle and I gifted it to his security.
“They had to take the liquid from the bottle to make sure the liquid was safe and it was not maybe poisoned or what not and then it was gifted to Vladimir Putin.
"I haven't got to speak to him since to see what he thought of it, although I'm sure he did have a taste and I'm sure he enjoyed it."

The pair met during the 2018 World Cup, when Putin reportedly invited McGregor to watch the World Cup final between France and Croatia with him.
McGregor thanked the Putin and even referred to him as one of the “greatest leaders of our time” after the game.
He posted: "Today I was invited to the World Cup final as a guest of Russian President Vladimir Putin.
"This man is one of the greatest leaders of our time and I was honoured to attend such a landmark event alongside him.
"Today was an honour for me Mr. Putin. Thank you and congratulations on an amazing World Cup."
