Anthony Joshua has continued to celebrate his 29th birthday after he was filmed hilariously dancing around the gym in just his boxers.

Joshua began his birthday celebrations after turning 29 on Monday as he shared a snap of himself with a giant chocolate cake, along with a video where he shouts ‘one life’.

The heavyweight champion appears to be in no mood to let the celebrations fizzle out though and was also captured unleashing some moves to hit song ‘Smile’ by Lil Duval.

Joshua can be seen thrusting his hips and waving his hands in the air as the song is blasted around the gym during a break in his workout.

He is currently enjoying some downtime after beating Alexander Povetkin by knockout in his last bout, before deciding who to face next.

Celebrations began on Monday when AJ held a sparkler in one hand as he posed for a photo while dressed in a white shirt with his glasses on.

The now 29-year-old has a record of 22 wins from 22 fights, including 21 by knockout.

His next fight is already confirmed for next April at Wembley, although the challenger is yet to be decided.

He had been tipped to face Deontay Wilder but now Eddie Hearn claims the American’s camp will not discuss a deal before the Tyson Fury fight, and so will not be ready in time.

Hearn said: ‘It doesn’t have to be Whyte if it isn’t Wilder but Whyte is a good alternative for us. It could also be (Jarrell) Miller in New York. That would be a big fight over here.

‘Our plan is still April 13 at Wembley but it isn’t looking good for Wilder. We would keep Wembley for Whyte, but if it was Miller it would be a similar time (in April) in New York. Miller could sell tickets and believe me he is a handful.’
