David Gest has been asked by Matt Willis, formerly of Busted, to be the best man at his wedding.
The two met during 'I'm a Celebrity?get me out of here' and were in the final together. The pair formed a strong friendship, much to the surprise of viewers and fellow junglers.
Willis, 23, is planning his marriage to fiance Emma Griffiths, an MTV presenter.
He told the Daily Mirror: "David is probably my best mate right now. I speak to him every day and hang out with him about three times a week."
He said of his friend: "We're completely different and there is a 30-year age gap, but it doesn't ever come into play. He's a really great, funny guy."
The wedding will take place in August next year.
Mr Gest, a music producer, is no stranger to weddings, having famously been married to Liza Minelli, a relationship which brought him much fame.
This is not the only wedding the celebrity show has resulted in. Katie Price and Peter Andre are now expecting their second child.
