Tamara Ecclestone hired two lesbians to perform at her sister Petra's bachelorette party.
The 27-year-old socialite surprised her younger sibling and her then-fiance James Stunt - who tied the knot in a lavish Italian ceremony last month - with a bash featuring pole dancers and lesbian performers who poured hot wax over each other.
Tamara said: "I turned my living room in to a strip club with pole dancers, made skittle vodka shots and hired two lesbians from The Box nightclub to pour hot wax all over each other."
Despite being worth £3 billion, the heiress - whose father is Formula One boss Bernie Ecclestone - insists she is not "a princess", and enjoys flying on budget airlines and watching "tacky" reality TV shows.
Tamara - whose own three-part UK fly-on-the-wall show 'Tamara's World' airs later this month - told the Daily Star newspaper: "I'd love to be a bartender, that would be great. And I fly on Ryanair.
"People think I act like a princess but I really don't. And I love watching all those tacky reality shows too, like 'Jersey Shore', 'Keeping Up with the Kardashians' and 'Girls of the Playboy Mansion'."
