She’s been mobbed by fans night after night following her performances in Cat On The Tin Roof.
And Sienna Miller seemed in great spirits as she greeted the well wishers ahead of another triumphant turn on the stage on Friday.
Looking casual yet chic as she headed into the Apollo Theatre, the 35-year-old actress opted for an oversized baby pink jumper before she changed into red tracksuit bottoms to head home.
The blonde bombshell looked as lovely as ever in her knitted jumper, which featured eye-catching cut out detailing across the side.
She teamed the garment with loose fitting grey mom jeans, whilst she slipped her feet into quirky yellow heels.
Later in the day, Sienna changed up her ensemble as she donned scarlet jogging bottoms and an oversized grey hoodie.
Sienna is currently starring in Tennessee Williams’ play Cat On The Tin Roof, alongside Skins actor Jack O’Connell.
She has received rave reviews for her performance as Maggie in the drama, which runs until October 7.
The Benedict Andrews’ directed play centres around the sexual tension between her character and her alcoholic husband Brick, who some believe is in denial about his homosexuality.
Sienna sparked false engagement rumours earlier this month after accidentally leaving a a piece of costume jewellery on while leaving the theatre.
The sizeable ring set tongues wagging about potential wedding bells for her and her director boyfriend, Bennett Miller, 50, who she met on the set of the 2014 film Foxcatcher.
However, a source close to Sienna later dismissed the claims as a ‘silly mistake’ and said there was no engagement.
Sienna shares daughter Marlowe, five with her former fiancé Tom Sturridge, whom she dated from 2011 to 2015.
