Are the Ecclestone sisters becoming the new Hiltons?

Taking Los Angeles by storm, British socialites Petra and Tamara Ecclestone stepped out Friday night and headed to celebrity favorite Boa Steakhouse for a double date.

The 22-year-old Petra and her husband of one week, businessman James Stunt, were met at the restaurant by Tamara, 27 and her boyfriend Omar Khyami.

Petra, who married James in a lavish $6.5 million ceremony last weekend -- attended by sisters Paris and Nicky Hilton, by the way --  put her bridal body on display in a form fitting animal print mini-dress covered with a chic cropped leather jacket.

Meanwhile brunette beauty Tamara, who is rumored to be getting her own reality show, showed off her model physique in a daring green Herve Leger bandage dress which she paired with Christian Louboutin stilettos.

Earlier in the day the women, whose father is billionaire Formula 1 boss Bernie Ecclestone, did what any good heiress should do -- shopped!  They each hit up several boutiques along famed Rodeo Drive in Beverly Hills.

Newlywed Petra also took delivery of a surprise wedding gift from her new husband. She received a brand new white Rolls Royce Phantom, worth around $250,000, that was delivered to her hotel Friday morning, complete with a bow on top.
