The Hollywood star then posted a second snap, showing off her coveted new trophy and the stilettos she wore. Her wrinkle-free ivory gown lay over a bathtub. 

“No wrinkles… harder than it looks! Somewhere between these two photos, my peers gave me a gift I will cherish and a night I will never forget,” she captioned the post.

Jennifer beat fellow nominees Olivia Colman, Helena Bonham Carter, Jodie Comer and Elisabeth Moss to win outstanding performance by a female actor in a drama series, lifeandstylemag.com reports.

In addition to her big win, the star was also part of the most viral moment of the evening – her backstage reunion with ex-husband Brad Pitt.
