The newest heir in town, Petra Ecclestone, 22, met up with sisters Paris and Nicky Hilton, and Brandon Davis for a casual evening out. Petra's new husband James Stunt was also along for the fun.

Petra, who recently parted with $85 million of her daddy's -- Formula 1 boss Bernie Ecclestone -- money to purchase Candy Spelling's mansion for $85 million, seems to be settling in nicely to her new life in SoCal.

The Hilton sisters have been her pals for years, and both attended her lavish wedding last month.

Davis, the grandson of the late oil baron Marvin Davis, played middleman on Petra's estate purchase, reportedly suggesting to Petra that she buy it and then hooking her up with the Hilton girls' dad, real estate broker Rick Hilton, to represent her in the deal.

At first glance, it seemed like an unlikely pairing --  millionaire Brit heiress Petra Ecclestone and Hollywood's convicted felon heir Brandon Davis sharing a friendly lunch Saturday -- but RadarOnline.com has photos.

Actually newlywed Petra, heir to daddy Bernie Ecclestone's Formula 1 fortune and Davis, whose granddad was oil mogul Marvin Davis, have been acquaintances for years and have mutual friend Paris Hilton in common.

Casually dressed in a plaid shirt, Davis joined Ecclestone and her husband James Stint, for a laid back lunch at Nello restaurant.

Davis reportedly was the one who suggested to 22-year-old Ecclestone that she purchase Candy Spelling's 57,000-square foot, $85 million mansion, a deal which Paris' dad, Rick Hilton, a real estate broker, handled.

Paris and the rest of the Hilton family were among the 250 lucky guests to attend Petra's $6.5 million wedding to Stint at in a castle in the Italian town of Bracciano last month.

While Petra has recently made headlines because of her massive fortune and big spending habits, her L.A. pal most often catches the attention of the media -- and the police -- due to his hard-partying ways.

As RadarOnline.com previously reported, Davis, 32, was arrested in April for felony drug possession and assault following an incident at the Roosevelt Hotel in Hollywood.  In June, he pleaded guilty to the cocaine possession charge and no contest to battery, a misdemeanor, for which the judge sentenced him to a drug diversion program.

Back in 2006, Brandon checked into the famous Promises rehab facility at a cost of $75,000-per-month.
