A few weeks after attending a New York Knicks game with her toyboy Oli Green, Extrapolations star Sienna Miller was spotted in the Big Apple, yet again, chatting with a gal pal while sporting a casual yet luxurious look on Tuesday.

The 41-year-old Golden Globe nominee – who relies on stylist Kate Young – paired her $860 white Gucci ‘Princetown Leather Slippers’ with ripped blue jeans, a white tank top, and a black baseball cap.

That same day, Sienna gushed over her My Mother’s Wedding castmate Scarlett Johansson while appearing on the iHeartPodcast podcast, Table for Two with Bruce Bozzi.

‘I went to make a movie and I made a best friend,’ Miller said.

‘I know she’s talked to you on this show and you’ve known her for years. She’s one of the most spectacular women I have ever met in my life.’

The Manhattan-born Brit, the 38-year-old Oscar nominee, and Emily Beecham portray three sisters reuniting in England to attend the third wedding of their twice-widowed mother Diana (Kristin Scott Thomas) in the family drama.

My Mother’s Wedding marked the 62-year-old Oscar nominee’s feature directorial debut, which she wrapped last June, but there’s been no new update on film festival screenings or distribution.

Last November, Sienna wrapped her mystery role in the first of Kevin Costner’s planned four-part epic western, Horizon: An American Saga, for Warner Bros. Pictures.

‘I am so excited to go on this epic journey with such a legendary actor and director at the helm,’ Miller told Deadline last August.

‘The story is riveting. I am very honored to be a part of it.’

On April 17, the 68-year-old Oscar winner began production in Utah on the second film, but it’s unclear if the Anatomy of a Scandal actress will be involved in part two.

The expansion of the American west flick spanning 15 years also features Sam Worthington, Jena Malone, Luke Wilson, Giovanni Ribisi, Thomas Haden Church, Michael Rooker, Jamie Cambell Bower, Isabelle Fuhrman, Michael Angarano, and Danny Huston.

Sienna will also portray Groucho Marx’s secretary Erin Fleming in Oren Moverman’s upcoming biopic Raised Eyebrows opposite Oscar winner Geoffrey Rush.

On the personal front, Miller is mother to 10-year-old daughter Marlowe Ottoline Layng from her four-year relationship with ex-fiancé – Sandman star Tom Sturridge – which ended in 2015.

‘She’s got her own sense of self and style,’ the Independent Spirit Award nominee told Vogue earlier this month

‘Mine was much more eclectic. Hers is cool and really chic and quite nineties…She loves me for being the ratty mum that I am but she is much more put together than I am, so sometimes she appreciates it if I wear a bit of make-up and a heel. She loves the sound of a heel. I think she associates the sound of heels with a “together mother.”‘

Sienna even borrows from Marlowe’s wardrobe on occasion: ‘I’ve lost a lot of hoodies, but I steal her clothes, too. Her little T-shirts are quite sweet over a vest and her jumpers are really nice and cropped.’
