Justin Bieber meets Keegan Allen of 'Pretty Little Liars'

keegan-allen-justin-bieber.jpgSaturday (Oct. 23), "Pretty Little Liars" star Keegan Allen met teen heartthrob Justin Bieber. Squee!

Allen tweeted a picture of them together (left), along with the following messages:

" Hey, Justin Bieber is a really cool guy!"

I was just chilling in bev hills and I struck up a convo with him- he is really chill."

We love it when two of our celebrity obsessions come together randomly - synergy!

We were recently on the "Pretty Little Liars" set and Keegan was one of the cast members we got to chat with. Look for a post in the coming weeks where he teases what Toby has been up to since his arrest in the midseason finale.
