Mike Tyson has reminded Jake Paul that he is coming for $1 million after winning the bet.
The legendary boxer also reminded him that they have a dinner date as well.
Tyson came out of retirement last November at the age of 58 and lost to Paul in the fight.
Around 50 million people watched Katie Taylor’s rematch win over Amanda Serrano in a historic trilogy bout.
The latest win came two years after her initial victory.
Paul – who promotes Serrano – put $1m (£750,000) up in a wager against Tyson – who was backing Taylor.
Tyson insisted he must also be taken out for dinner by the YouTuber-boxer if he won.
The 59-year-old posted: “Congrats to @KatieTaylor and @Serranosisters on the trilogy fight on Netflix.
“@jakepaul see you at dinner to collect my million!”
Taylor said: “I just want to thank Amanda Serrano as well, what an amazing fighter, we’ve made history here.
“I thought I boxed very smart, very well. She wasn’t catching me with much.
