We all saw Spencer (Troian Bellisario) lose her marbles on Pretty Little Liars last night (March 5). Between her hallucinations and possibly joining the "A" team, we're worried about our girl Spence. But hey, at least in real life, she's kicking back and joking around. 

"Spencer might be crazy on #PLL right now but she is hilarious when we are on a shoot together," Shay tweeted yesterday (March 5), along with a photo of her and Troian making funny faces with cartoon mouths. So when can we be BFFs with you girls?

Shay and Troian star in a new short film together called Immediately Afterlife. In the movie, which will be submitted to festivals later this year, Shay and Troian play Marissa and Bennett, respectively, the sole survivors of a religious cult’s mass suicide attempt. Learn more about the flick and sound off in the comments below!

Catch the next episode of Pretty Little Liars on Tuesday, March 5, 2013 at 8 p.m. ET/PT on ABC Family.
