Sienna Miller is Single and Models Her Spring Twenty8Twelve CollectionTwo pieces of designer/actress Sienna Miller news this morning — first the real shock, "I'm single" she announces. Um, ok. Good. Currently rehearsing for her new West End play, she is apparently trying to take the pressure off her male co-star who is being linked with her romantically. But the poor gal lands up just coming off a bit defensive. Never-the-less, we wish her well with her month of singleness and hope that she is happy. Secondly, Sienna modeled the new spring collection from Twenty8Twelve (the line she designs with her sister Savannah) for Nylon magazine. It's all quite nice — most of the boho stuff you would expect with a slightly cleaner, sweeter edge. It will be available online later this month from a bunch of stores, including asos.com which delivers to SA.
