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.
