They're two of the most popular sporting stars of their generations.
And tonight, boxing legend Muhammad Ali, 70, teamed up with English football star David Beckham to present a prestigious new award.
The men shared the stage as they presented Afghan refugee Matiullah Haidar with the inaugural Generation Ali Beyond Sport Award at a London reception.

The awards marked Ali's first public appearance in the build-up to the Olympics, which kicks off on Friday.
The ceremony celebrates young people who have inspired their peers through sport.
Haidar, 19, who came to the UK as a refugee after losing most of his family in the conflict in Afghanistan, now coaches sport and supports refugees as a translator.
Speaking tonight, Beckham, 37, said: 'Muhammad Ali is one of the most inspirational sportsmen of all time. He is a global icon, and he has touched so many lives.

'It is a true honour to join with him to present the Generation Ali Beyond Sport Award to one of this incredible group of young people.'
Although Ali isn't expected to take part in Friday's opening ceremony, Beckham confirmed he would have a 'small part' in the extravaganza.
Beckham was controversially snubbed a place in Team GB men's football team by coach Stuart Pearce.

However, as he was such an important role of London's Olympic bid in 2005, the games chairman Lord Coe has asked him to be involved.
Becks told ITV: 'For him to keep me involved I feel very privileged. He has talked to me about a few things. I am playing a small part in the Olympic ceremony.'
Although he has declined to give away any more details: 'I would love to but I can't because it's exciting, it's going to be good.'
Mohammad Ali, a father of nine, was diagnosed with Parkinson's disease in the early 1980s.
He has fought his dignified battle with the illness for 26 years and despite looking increasingly frail he continues to make public appearances, refusing to shy away from the limelight.
The decision has endeared him to millions of fans and has helped raise awareness of the degenerative disease.
