Tyson Fury (25-0, 18 KOs), the former IBF, IBO, WBA, WBO heavyweight champion who calls himself the 'Gypsy King', has offered his services to help create a little gypsy prince or princess - at the cost of £50,000 a pop.

The 28-year-old has taken to Twitter to make the pricey offer, posting a photo of himself in the ring holding his championship belts and writing: "Get a son off the undisputed heavyweight champion, studding fees £50k plus vat [value added tax] a pop".

Fury has been married to wife Paris since 2009.

He hasn't been in the ring since he defeated division ruler Wladimir Klitschko in a major upset in November 2015.

Fury was forced to pull out of his highly anticipated rematch with Klitschko in June last year and vacated all three of his belts, although he was about to be stripped after failing to prove his medical status to the WBO and IBF boxing chiefs.

The vacant WBO belt was won by Joseph Parker after he defeated Andy Ruiz Jr in December. Anthony Joshua now owns the IBF title, and the vacant IBO/WBA belts will be at stake next Saturday when Joshua faces Wladimir Klitschko.

In early March, Fury announced his return to the ring with a bout on May 13, but that is highly unlikely as the boxer is not training and weighs well over 300 pounds.

Fury is set to land in New Zealand next month to support his cousin Hughie Fury as he takes on Parker on May 6th in a mandatory showdown.
