Anthony stunned his Twitter followers in April 2016 when he revealed he had a secret child who was six months old – son Joseph.

Joshua, from Watford, Hertfordshire, captioned an adorable image of his son: ‘Achieved one of my goals as a professional boxer! Now the dust has settled it’s time to relax with my lil champ JJ’.

Baby Joseph Bayley Temiloluwa Prince Joshua was born at Watford General Hospital on October 6.

Joshua went to great lengths to keep the news of his son a secret, including buying a £500,000 flat in Finchley, north London for his on/off girlfriend Nicole, The Sun reported.

The couple are said to have had a turbulent relationship over the years, with Joshua being linked to singer Rita Ora, 25, and model Cara Delevingne, 23.

It was good to see Anthony in high spirits over the festive period, despite missing out on a New Year honour just days after he was snubbed in the BBC Sports Personality vote.

The boxer, who beat the former long-reigning champion Wladimir Klitschko in a thrilling contest in front of 90,000 people in April, was also the clear bookmakers’ favourite to land the Sports Personality Of The Year gong.

But the popular gold medal winning Olympian, who boasts 5.2 million followers on Instagram, failed to even make the top three despite two epic prize-fights this year.

The north Londoner, who was awarded an MBE for his 2012 Olympic heroics, again appears to have been slighted after missing out on a New Year honour.

Real name Anthony Oluwafemi Olaseni Joshua, the British boxer of Nigerian descent moved to a perfect 20 knockouts from 20 fights, while winning a legion of fans for his brutal bouts – including the now infamous slug-fest at Wembley Stadium in April.

Pitted against the Ukrainian Klitschko, who along with his older brother Vitali ruled the heavyweight division for more than 10 years, Joshua endured a vicious onslaught where he was floored by the revitalised former champion and very nearly stopped.
