Things may have just gotten awkward on the set of Pretty Little Liars.

Ashley Benson (Hanna) posted a photo of herself and Lucy Hale's (Aria) ex-boyfriend, Chris Zylka, hangin out at the airport over the weekend. Lucy and The Secret Circle actor dated for six months and broke up last fall. So why was Ash spotted getting silly with Chris on Instagram?

Despite the couple’s rough breakup, it looks like Ashley and Chris are still good friends. Ashley wrote, "Look who came to hangout at the airport." We already know that Ash is in Austin, Texas for SXSW, so maybe Chris was making his way to the festival himself when he ran into Ash in the terminal. Or maybe they coordinated a pre-flight hangout sesh.

Whatever the case may be, we're sure Lucy will make light of it. After all, following the split, Chris said he would continue to be Lucy's biggest fan, so we're sure these two have worked out their differences and remained friendly.

What do you think is going on in the photo? Sound off in the comments below!
