But what is the net worth of one of the most successful British boxers of all time?
Khan, 30, started his career as a lightweight boxer, moving through the size categories over the years. His most recent fight was with Saúl Álvarez in May 2016, which saw Khan lose.
However in boxing a loss is still a money-spinner, so the Bolton native was probably not too worried.
Notable wins over his career include at the Olympics in Athens in 2004, when he won a silver medal.
Financially, Khan has also been highly successful, negotiating money from fights as well as TV rights, a lucrative deal.
According to TheRichest.com, Khan was worth £22million as of 2013, with no reliable updates on his fortune since then.
Whilst his boxing career has been success, Khan has a colourful personal life.
He wed Faryal Makhdoom in 2013, and the pair have one child with another on the way.
But they have undergone a very public break-up this year, recently reconciling – with their break-ups and make-ups played out over social media.
And a lawyer has now revealed if they do divorce, Faryal could receive half of Amir Khan’s fortune.
Harold Walker has said that she could receive a large sum when the pair divorce.
“The starting point will be a 50:50 division of all assets. Faryal will do very well,” he told the Daily Star.
US Instagram star Faryal has undergone a transformation since the pair met – a plastic surgeon commented to Express.co.uk.
Faryal is not a stranger to cosmetic enhancements and was filmed earlier this year having a nonsurgical cheek augmentation and lift at Simon Ourian’s clinic in Beverly Hills.
Dan Marsh, cosmetic surgeon at The Plastic Surgery Group, Harley Street, spoke exclusively to the Express.co.uk about what he believes Faryal might’ve had done to her face.
Although he has never met the 26-year-old, and neither has he consulted her about plastic surgery, he believes she may have been under the knife.
