Formula 1 boss Bernie Ecclestone is said to have splashed out an estimated 1.3 million dollars for his youngest daughter,Petra Ecclestones wedding next week. The three-day celebration near Rome will include performances by Eric Clapton and The Black Eyed Peas. The 80-year-old motor-racing supreme had thrown a 6,00,000 pound engagement party for his 22-year-old Croatian English socialite and her 28-year-old businessman beau James Stunt,headlined by Rihanna. Petra is Bernies little girl. Hell do anything to make her happy and she wants a wedding to leave her society chums green with envy, the Mirror quoted a guest as saying. After Rihanna performed at the engagement bash,it was a tough ask to trump that. But Petra had her heart set on Fergie and the Black Eyed Peas and used her connections. Eric rarely gives public performances but is a close friend of Bernies. Hell be singing as the bride and groom take their first dance. It will be a magical evening, the guest added. In an estimate,The Black Eyed Peas will cost £750,000 pounds,Clapton £230,000 pounds and the rent of the Italian castle £310,000 pounds,including catering,guests accommodation and a £40,000 firework display at midnight.
