Credit: Ashley Benson's Instagram Photo: Ashley Benson Hangs With Chris Zylka on His Birthday

Lucy Hale (Aria) and former boyfriend Chris Zylka may be dunzo, but that's not stopping Ashley Benson (Hanna) from being his pretty little bestie.

Pretty Little Liars actress took to Twitter yesterday (May 9), posting a photo of herself out and about with Chris for his 28th birthday celebration. "Birthday boy," Ashley wrote, along with the pic.

This could be awkward for Lucy, but then again, she and Chris did break up back in September. Plus, Ashley and Chris seem to run in the same circle
and Chris is dating Originals star Phoebe Tonkin. So we're sure Lucy has fully moved on by now and is happy for the birthday boy.

What do you think of Ashley and Chris's friendship? Sound off in the comments below!
