The heavy hitters are in town for one of the biggest heavyweight boxing events in years this weekend in boxing.
It is thought that Joshua vs Dubois this weekend at Wembley will see more than 96,000 people at the event.
What a number and what an event, Lennox Lewis the former undisputed heavyweight champion is in the house for it:
Lewis knows all about big time heavyweight title fights of course.
Only ever losing twice as a pro and avenging both defeats before he retired no less.
One of the most complete heavyweight champions of all time.
