Spencer Matthews has revealed his bar bill for close to half a million pound was a ''mistake''.

The 'Made In Cheslea' star shared a photograph of the receipt for £488,706.08 on Twitter after a night out in Morton's private members club in London's Mayfair on Saturday night (16.11.13).

But Spencer revealed the barmaid keyed in the wrong figure, he said: ''The female bartender was particularly attractive and we chatted as I ordered two Grey Goose sodas with fresh lime, and two shots of Patrone Silver Tequila.

''However on this occasion, trying to charm the barmaid was my downfall. She was distracted as she keyed in the bill and what should have been £48 ended up as £488,706.08.

''My heart skipped a beat or two and I was concerned that prices had gone up a bit since I'd last been at the club only two days before, but it didn't take Sherlock Holmes to work out the mystery of the six-figure bill.''

The 25-year-old hunk had tweeted the receipt with the message: ''Sh************t....'' and said he woke up the next day to more than 3,000 retweets and several people ''berating'' him for such an ''outrageously extravagant waste of money.''

Spencer was partying at the 2&8 nightclub in the basement of the Berkley Square venue, which was voted Best Private Members Club 2013, and is a hotspot for celebrities.

He wrote in his blog on MailOnline that he will donate the price of his original bar bill to Typhoon Haiyan Appeal and said the money he has left over after his Saturday night out will also go towards Christmas presents for his 'Made In Chelsea' co-stars.
