Sir Elton John is taking legal action against a banker who failed to honour a $1.1 million (£700,000) bid made at a charity auction.
At the singer's annual White Tie and Tiara Ball last year (10), Spencer Lodge won the chance to spend a day with the Rocket Man hitmaker.
But the banker has reportedly failed to honour a contract he signed pledging the money to the Elton John Aids Foundation.
After several attempts to contact Lodge, the singer is said to have instructed his lawyers to file suit against Lodge.
A source tells Britain's Daily Mirror, "Elton is not personally hounding the man and demanding the cash back but he is fully supportive of the legal proceedings to benefit the charity.
"The lot was a one-off opportunity to make his charity an astonishing amount of money. Organisers had actually secured another bid of £650,000 which, of course, they would have been delighted with.
"The feeling is Mr Lodge was at the ball, enjoying the plush surroundings a little too enthusiastically and didn't really know quite how much he was bidding.
"In the cold light of day, it appears he got cold feet and couldn't go through with the bid. Initially there was a misunderstanding as Mr Lodge was changing lawyers but still nothing has been resolved so that's why it has gone this far."
