Sienna Miller and Tom Sturridge at the Theater

Sienna Miller Supports Tom Sturridge in His New Show

Sienna Miller wore a fur coat with Tom Sturridge at the No Quarter press night in London.

Sienna Miller turned out to root for her fiancé, Tom Sturridge, in London last night. He stars in a production of No Quarter, a new show from 26-year-old playwright Polly Stenham, at the Royal Court Theatre. Tom is one of the show's stars, along with Zoe Boyle, who played Lavinia Swire in the second season of Downton Abbey.

Sienna's back in the UK following a big week in California. Sienna Miller attended the Globes Globes, wearing a dress from British designer Erdem, as a nominee for her HBO movie, The Girl. She wasn't ultimately a winner in the category of best actress in a miniseries or made-for-TV movie, since she was bested by Game Change's Julianne Moore. Nonetheless, Sienna hit the party circuit. She attended Globes hosts Tina Fey and Amy Poehler's afterparty at Soho House along with Robert Pattinson and Kristen Stewart. Now, though, Sienna and her daughter, Marlowe Sturridge, are back home in the UK with dad Tom.
