Ashley Benson (Hanna) looked like she had a blast at Coachella Music Festival over the weekend, living it up with her Pretty Little Liars co-stars, Tyler Blackburn (Caleb) and Troian Bellisario (Spencer). But those aren't the only famous faces Ashley rocked out with.

The PLL actress showed off this fun-filled photo on her Instagram over the weekend, showing off her party crew — that's right, Pretty Little Liars fans, Ashley chilled with Katy Perry (far right) during the festival. Worlds collide!

While Ashley looked laid back in denim shorts and a cropped top, our girl KP went for a more eccentric look (shocking, we know), with her patterned bikini top and matching shorts.

After you pick your jaw up from the floor, let us know what you think of this celebrity duo. Would Ash and Katy be the most awesome besties ever, or are they probably just party buds? Let us know your thoughts in the comments below!
