Shay Mitchell stripped down to celebrate a major YouTube milestone.

The Pretty Little Liars alum recently hit 3 million subscribers on her YouTube channel and shared her reactions with her fans.

In a YouTube video entitled, "I Ran Naked Through the Streets of LA!" Shay can be seen running down Sunset Boulevard topless.

"So I hit 3 million subscribers on YouTube and I am so, so excited," Shay says at the beginning of the video. "I can't tell you how much this means to me to have you guys coming along, especially since when I first started the channel it was uncharted territory and now it's just a learning experience every single week."
