Petra Ecclestone will be hosting a post-wedding bash at her new 56,000 square foot mansion in Holmby Hills, California, RadarOnline.com is exclusively reporting.
The stunning, mega-wealthy daughter of billionaire Formula One racing chief, Bernie Ecclestone, is marrying businessman, James Stunt in Rome at the end of August.
Petra, 22, bought her mega-mansion from Candy Spelling for a whopping $85 million dollars -- in cash!
"Petra will be throwing an over-the-top party at the house after she is married in Rome," a source close to the situation tells RadarOnline.com. "The party will likely take place in late September, early October. She is planning the party as her official coming-out party to Hollywood. The party will be for James and Petra, but leave no doubt, this party is going to be all about her."
The guest list for the post-wedding bash will read like a who's who in Hollywood, definitely including: "Paris, Nicky, Rick & Kathy Hilton," the source says. "Paris and Petra have been friends for years. Petra has been asking Paris for career advice, which Paris has been more than willing to share. In fact, Rick, who is a top realtor, sold the house to Petra."
