The Alfie star attended the glitzy ceremony in Los Angeles as a nominee for Best Performance in a Mini-series or Television Film for her role as Tippi Hedren in The Girl.
It was a rare public outing for the star, who gave birth to her daughter Marlowe with fiance Tom Sturridge in July, and the actress admitted she struggled to be away from her beloved first born.
She told E! News: "It's really nice (to be at Golden Globes), but I miss my baby! She's just got to the age where I leave and she cries so it's just heartbreaking. That's the milestone we're at, but it's good. It's lovely to be nominated and to be here."
The Brit lost out on the award to Julianne Moore, who picked up the prize for her portrayal of former US vice presidential hopeful Sarah Palin in Game Change.
