Sienna Miller launched her brand Twenty8Twelve this Thursday with a fussy fashion party at a private venue in Camden. The locals residing near the party venue seemed to be unhappy about the affair and complained about the barrage near The Dairy in King’s Cross caused by large cars of party goers.

An onlooker said “They came buzzing out like flies. Hooters were going off because cars blocked the road. It was chaos.” Another has to comment: “I wouldn’t have minded so much if Miss Miller had had the decency to warn us the event was taking place. It’s very rude.”

Sienna and her fashion designer sister Savannah went on with their celebrations that night at Whisky Mist night club in Mayfair where they were joined by the whole family.

Sienna Miller, in her signature style attire, was at Groucho Club in Soho last night. She was accompanied by Cilliam Murphy, her co-star in “The Edge Of Love”. They both are again expected to appear on the silver screen later this year in an upcoming file.After enjoying a private dialogue and fine wine at the Groucho Club in Soho, the couple moved to Jerry’s Club at 2am.

Rumored to be single again, party-loving Sienna Miller had a very busy night out when she hit up the Hollywood Dominos event in Mosimann’s in London.

She sat next to Kylie’s ex Olivier and played a few hands with him. She also enjoyed a drink with Josh Harnett and David Walliams. Sienna then spent the rest of her evening at the Jalouse nightclub. The flirtatious actress then left the club at 4:00 a.m. at the same time as Josh Harnett and looking like a woman sending out a loud message that she is moving on.

Sienna Miller cozied up to step sister Natasha Corrett at the opening party for Maya club in London’s hip Soho district. Miller’s step mother and guy pal Rhys Ifans also attended the late-night happening.
