PRINCE Harry racked up a bill of over £30,000 while partying in Las Vegas but never had to pay it, a new documentary has claimed.
Appearing on Channel 5's Spending Secrets of the Royals, biographer Katie Nicholl claims Prince Harry's costly expenses were covered by the billionaire owner after he waived the bill for the Royal.
While discussing Prince Harry's old spending habits, the royal expert claimed that he "ran up a £30,000 bill" while staying at the Wynn hotel in Las Vegas back in 2012.
But when it came around to settling his expenses, Katie added: "Steve Wynn, the owner of the hotel Harry was staying in, just wiped the slate clean."
It was during Prince Harry's stay at the luxury hotel in Las Vegas - where suites can cost upwards of £700-a-night - that the Royal was pictured naked in photos that were then leaked online.
Although the photos themselves were deemed an invasion of his privacy, The Sun recreated the photos of Prince Harry standing naked in the Las Vegas hotel room while covering his modesty.

However, the royal expert claims that this was not the only time Prince Harry didn't have to pay a bill.
While enjoying a night out in London's Mayfair in 2007, the royal expert added: "Prince Harry tried to pay with his Army identity card."
Having "racked up a pretty sizeable bar bill" while partying with friends and his then-girlfriend Chelsea Davy, Katie said: "The barman called for the manager to see exactly what to do about this transaction and the bill was waived."
Meanwhile, royal expert and editor of Majesty magazine Ingrid Seward added: "Prince Harry was, and probably still is, the party boy of the Royal Family.
"He just loved to go out drinking with his mates and go out clubbing."
But it would seem Prince Harry's extravagant spending prior as a young man in the army was only a warm-up for what would be his biggest party of all: his wedding day.
Breaking down the cost of Royal Wedding, Katie added: "The majority would have gone on security, which was the biggest single expenditure.
"£286,000 or thereabouts was spent on catering for the evening event, £193,000 on drink alone, a further £100,000 on the flowers which beautifully adorned St George's Chapel and then £387,000 on Meghan's wedding dress."
In comparison, Kate Middleton's Alexander McQueen wedding dress is estimated to have to cost £250,000 when she married Prince William in 2011.
The documentary also reveals that the Queen Mother also lived extravagantly during her years at Clarence House.
Royal wine waitress Pippa Penny revealed: "At the age of 97, she was in hospital having an operation on her hip and she smuggled 12 bottles of Krug champagne into the hospital to make her stay a little more comfortable and enjoyable.
"A bottle of Krug can fetch up to £150."
It was this extravagant spending that led to The Queen eventually having to subside her mother's spending to £1.5m a year, according to Katie Nicholl.
She added: "When the Queen Mother died, she actually had an overdraft with Coutss bank of £4m which was left to the Queen to clear."
Spending Secrets of the Royals airs on Channel 5 tomorrow at 10pm.
