The star, who is currently filming the second season of the hit HBO show, was photographed wearing a bright pink ensemble, reminiscent of her character in Legally Blonde.
Witherspoon, 42, was photographed standing beside a black car wearing a silver sequined top with hot pink pants and a pink and red track jacket.
She wore her blonde hair in a puffed curly ‘do, which she accessorized with gold hoop earrings.
While there is no synopsis available for the upcoming season of the series, this might be a sign that another costume party scene is in the works.
The season finale of Big Little Lies ended with a costume party at an extravagant school fundraiser attended by Witherspoon, Nicole Kidman, Shailene Woodley, Laura Dern and Zoe Kravitz’s characters.

“I was excited about my meeting on Legally Blonde 3 that I wore my pink dress,” the actress told fans.
“It’s true,” she wrote on social media June 7, captioning a video of herself in the two piece as she drifted on a blue pool float.
Plot points or returning cast members haven’t been announced yet for Legally Blonde 3, but MGM announced the third installment will hit theaters on Valentine’s Day, 2020.
