It's hard to believe, but it's already been 15 years since Legally Blonde first bent and snapped its way into our hearts. In honor of the milestone, Elle Woods (aka, Reese Witherspoon) took to Instagram with a celebratory call to action for the movie's fans.

"Alright, y'all! Can you believe it's Legally Blonde's 15th anniversary tomorrow!?" Witherspoon, 40, wrote alongside a video message (below). "Celebrate with me on @instagram ..."

In the video, the actress asks fans to share Instagram photos of anything that reminds them of the film along with the hashtag #legallyblonde15. Your reward? A very special tutorial.

"You guys, tomorrow is the 15 year anniversary of Legally Blonde," Witherspoon—in her best Elle Woods voice—says excitedly to the camera while waving a pink fluffy pen in front of her face. "So, make sure and share pictures of you wearing pink, a picture of your pet, your law degree—anything that reminds you of Legally Blonde—and hashtag it #legallyblonde15. I might even show you show to do the bend and snap!"

So iron your best pink shirt and take Bruiser to the groomer, and don't forget to use the hashtag, #legallyblonde15!
