The Aussie actress, 44, hit the Shamrock Social Club in West Hollywood the day after taking home the trophy for her role in Blue Jasmine. And she came with a friend and fellow nominee: American Hustle's Amy Adams, 39.
The two women were also joined by their significant others – Adams's fiancé Darren Le Gallo and Blanchett's husband Andrew Upton.
Blanchett left the parlor sporting a black bandage on her left wrist.
What might the new ink be? The stars' reps declined to comment, so we'll have to wait to see.
