"It's a dream come true that I got to work with the most incredible person!! And yes I know, we're haunting," Maddie captioned her Instagram with Troian. Fellow cast mate Ashley Benson also shared a shot of her and Maddie looking pretty scary.
We'll have to wait until her episode airs in July to find out just exactly what her role is, but it seems she also does some dancing since she thanked choreographer Travis Wall on Instagram. "A big thank you to the amazing @traviswall," she captioned their pic. "You created something so cool but creepy at the same time."
Can't wait to watch!
