Celebrities generally aren't afraid to pose naked on social media [1], but Shay Mitchell just took things to a whole new level. To celebrate reaching three million subscribers on her YouTube channel [2], the Pretty Little Liars [3] alum honored a bet she had made with a friend while on vacation in Morocco [4]: running around the streets of LA . . . naked.

For the fun occasion (which was caught on camera), Shay wore a unicorn mask and a practical pair of white sneakers [5], but it was her cute choice of underwear that immediately caught our attention. The lime green briefs that read "Nice Buns" made for a perfect tongue-in-cheek moment, proving that the actress is more than a swimwear queen [6]. Ahead, watch the full video and shop similar panties, whether you're planning on running around naked or not.
