The actress, 45, shared a throwback photo of her posing with the signature pink bunny costume she donned as Elle Woods on Thursday. In an Instagram post, she shared a photo of herself holding up the corset and bottoms with the ears perched atop her head. A gray wardrobe box sat behind her, labeled Legally Blonde. All that was missing from the look were the bright pink tights she wore in the 2001 film. "MOOD on Halloween… 👻🔮☠️🎃" she captioned the post, which also featured some of her other looks from past Halloweens, including a life-size banana and a corpse bride.

"Omigod you guys ….#LegallyBlonde premiered 20 years ago TODAY!" Witherspoon wrote in the post's caption. "Time flies when you're busy using legal jargon in your every day life." The Oscar winner went on to say that "playing Elle Woods was the role of a life time and I'm so honored to have been a part of sharing her story with you all." Luke Wilson Says He'd Come Back for Legally Blonde 3: 'We'll Just Have to See What Happens' "Every meme, graduation cap, musical number, halloween costume and bend & snap has brought me so much JOY over these past two decades!" she raved. "I wonder... what will Elle do next?" Some of the images Witherspoon shared at the time included shots from the movie's alternate ending, which featured Elle sharing a kiss with Emmett (Luke Wilson) on the courthouse steps and a blonde Vivian (Selma Blair).

"I can't wait to see what people will think of the way we wrote Elle Woods.

When asked if fans can expect to see references to iconic moments in the original two movies, Kaling confirmed: "Bend and Snap is forever. We definitely have a lot of fan favorites from the original movie."
