Ashley Benson (Hanna) seemed to have a great time at Coachella over the weekend, posting photos of herself hanging with Pretty Little Liars co-stars Troian Bellisario (Spencer) and Tyler Blackburn (Caleb). She even spent time with pop star Katy Perry. However, there are two people who really left Ash star-struck.

"When I got superrrrr embarrassed to meet @teganandsara," Ashley tweeted, along with a photo of herself smiling with Canadian indie rock band Tegan and Sara. It looks like someone's a big fan!

If you can't get enough of Ashley's music festival adventures, check out more pics from her fun weekend!
