Anthony Joshua was given congratulations by celebrities in his dressing room last night after his victory against Carlos Takam.
Joshua retained his IBF and WBA heavyweight belts by defeating Takam in ten rounds.
Joshua knocked down the Frenchman in the fourth, as the 36-year-old struggled on despite suffering a cut over his left eye.
80,000 spectators packed out the Principality Stadium in Cardiff in what was one of the fastest-selling events in the venue's history. Millions across the world looked on as Joshua's record of 20 knockouts in 20 fights was preserved.
In his first fight since Wladimir Klitschko at Wembley Stadium, Joshua utilised his height, size, speed, and quick reactions, showing incredible stamina throughout the fight.
Boos rang around the arena at the end, however, and Takam couldn't hide his disappointment when referee Phil Edwards stopped the fight.
Joshua said after the bout: "For all of you who wanted to see him unconscious on the floor, it was unfortunate that the referee stopped the fight. But that wasn't my decision. I did my job and it was a good fight."
Tributes were paid on Twitter to both Takam and Joshua from boxing personalities Lennox Lewis, Carl Frampton, and Barry McGuigan.
Despite having an ice-pack over his eye, and one of his hands in a bucket of ice to help the healing, Joshua was happy to see the celebrity duo in his locker room after the fight.
The 28-year-old is pictured with the 'Luther' star with the pair grinning and clenching fists to the camera.
Irish actor Farrell, known for his performances in Minority Report, In Bruges, and Horrible Bosses, saluted him with a friend before taking photos with the heavyweight champion.
Manchester United and Sweden forward Zlatan Ibrahimovic also wished the boxer good luck prior to the Cardiff fight. Joshua was laughing with delight at the sight of the 36-year-old, who was looking as nonchalant as ever.
Joshua has since said he wants to call out Joseph Parker and Deontay Wilder as potential opponents in 2018.
