Pretty Little Liars star Ian Harding is one of the sweetest, friendliest actors we’ve come across, so it’s no surprise that he’s branching out with his celeb pals. In addition to cozying up to all of his friends on PLL, he was recently spotted taking an adorable pic with a female star of Once Upon a Time!

The lucky lady tweeted a photo of him pointing at the camera while she gave a thumbs up at a recent event, captioning it, “Yessssss. Photobomb! @ianmharding what a sweetheart!” and they look to be having an amazing time.

So, who is the girl in question? Jamie Chung, aka Mulan on the hit fairy tale drama. They were doing 24 Hour Plays, an annual event in Los Angeles that brings actors together for six short plays within 24 hours. Ian performed with Jamie, Molly Simms, and David Krumholtz, and they all posed for a fun group pic after (below).

Unfortunately, we can’t see the play for ourselves since they are only performed once, but hey — maybe Jamie will stop by PLL sometime! She does work closely with Julian Morris (Wren) on OUAT, as he plays Prince Philip on the ABC show.

Did you know Jamie and Ian were pals, or were you surprised? Sound off below!
