The 29-year-old heavyweight boxer holds the WBA, IBF and WBO titles all after his unification clash with Joseph Parker back in March.
He was previously awarded a MBE back in 2013 for his success at the London 2012 Olympics after winning gold in the heavyweight boxing.
Prince Charles also awarded Joshua his MBE back in 2013. When the imposing fighter, who is 6ft 6in, shook hands with the Prince after the presentation five years ago, he said Charles joked with him, saying: ‘Shouldn’t you be playing basketball?’
Dressed in a black suit jacket and grey trousers, Joshua once again beamed with delight on his visit to the Palace as he accepted the honour from the Prince of Wales.
The pair were photographed shaking hands and then in discussion in front of the packed audience.
Joshua retained his heavyweight title back in September when he took on Alexander Povetkin. He’s currently taking a short break from boxing before he heads back to the ring with a new opponent at Wembley.
