And you thought Kim Kardashian’s wedding was over-the-top.
British heiress and socialite Petra Ecclestone, the 22-year-old daughter of former Armani model Slavica and billionaire Formula One CEO Bernie Ecclestone, exchanged vows Saturday with businessman James Stunt in a three-day event just outside of Rome.
The wedding took place at Castello Orsini-Odescalchi, the castle where Tom Cruise and Katie Holmes wed in 2006. The bride arrived to the nuptials in a white Rolls Royce and wore a gown by Vera Wang for the outdoor ceremony.
Eric Clapton and the Black Eyed Peas performed for 350 guests – including the Hilton sisters and Princesses Beatrice and Eugenie – at the wedding reception, which also featured fireworks and an acrobatics show. Their engagement party in London in May included a performance by Rihanna.
“The wine and champagne list was really out of the ordinary – even for our standards,” a employee of the company that catered the reception tells PEOPLE. “Exclusive French wines were flown especially in.”
A media darling in the U.K., Ecclestone made headlines in the States in July, when she purchased Aaron and Candy Spelling’s former home in Los Angeles for $85 million. “The Manor” is the largest residence in Los Angeles County.
Ecclestone works as a fashion designer and will release her new Starks handbag line in the States this fall. She had meningitis as a child and now serves as an ambassador for the Meningitis Trust. She and Stunt have said publicly that they’ve signed a pre-nuptial agreement.
