The 25-year-old hunk posted a photograph of a bill for £488,706.08 on the micro-blogging site after an extravagant night in Morton's private members club in Mayfair, London.
It is not known whether the bill was paid for by Spencer, whose parents own the exclusive Eden Rock hotel in St Barths, but he tweeted the receipt with the message: "Sh************t...."
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.
Whoever did settle the bill paid using a debit card and heading out of the bar around 1.22am.
Spencer was educated at independent boarding school Eton near Windsor and become a broker before starring in the E4 reality series 'Made In Chelsea' with close friends.
He recently penned a book about his love life entitled 'Confessions of a Chelsea Boy' in which he also wrote about his travels to St Tropez and New York and his gambling with Hollywood stars.
