We are used to seeing Sienna Miller "paint the town red" with her party-loving night's out, but last night Sienna turned the huge London Eye landmark red, literally! The eye was lit up to support World AIDS Day and is also just in time for Christmas! Great that Sienna supports a important cause like that. She looked fab doing it as usual too! Sienna wore a furry Burberry jacket and combined it with red lips and red gloves, to match the red lights!
