Princesses Beatrice and Eugenie stepped out of Rome's Hassler Hotel earlier today accompanied by their mother, Fergie, en route to Petra Ecclestone's sunset wedding ceremony. The wedding festivities kicked off last night with an elaborate rehearsal dinner celebrating the couple. The heiress and her fiancé, James Stunt, reportedly invited 250 guests to the lavish event, including Paris, Nicky, Kathy, and Rick Hilton. Friends and family were shuttled to Odescalchi Castle prior to the wedding while the bride-to-be and her billionaire father, Bernie, were chauffeured in a Rolls-Royce. Petra walked down the aisle wearing a custom-designed Vera Wang gown, and shortly after the one-hour ceremony guests were serenaded by Andrea Bocelli. The music continued throughout the night with performances from The Black Eyed Peas, Eric Clapton, and David Guetta.
