As Pretty Little Liars barrels towards its series finale, we’re reminded of one guest star who made quite a creepy impression on viewers — Dance Moms alum, Maddie Ziegler!

Fans of the show may recall the 14-year-old's brief cameo during the first episode of Season 6, in which she appears as a deranged little girl in A’s dollhouse, who turns out to be a figment of Spencer’s imagination.

Of course the reality star got to flaunt her superior dance skills in the clip, which shows her leading Spencer into one of the bunker’s many rooms, though this one stores a broken bathtub and what appears to be an operating table.

At the time the episode aired, executive producer Oliver Goldstick opened up to EW about incorporating her scene into the narrative. “Maddie is represented by the same agency that I am. They called me last year toward the end of [Season 5] and said, ‘Can you put Maddie in it? Maddie’s a huge fan of the show.’”

He revealed, “After the dollhouse in the last finale, I thought, okay, we’re already in a place where we don’t know who was in that bunker besides our girls, so the idea was we would find a way to create, at least if not a legitimate sequence, a fantasy sequence.” So You Think You Can Dance star Travis Wall choreographed the finished product.

Although Maddie’s acting was limited to what she conveyed during the dance, the teen has since expanded her resume to include film roles. She recently voiced a character in the 2016 animated movie Leap! and stars alongside Naomi Watts and Lee Pace in the upcoming drama The Book of Henry.

She previously told Nylon, “I want to be an actress, so I’ve been auditioning lately. I’d love to be on scripted TV shows and movies, but not just one — I want to be in a lot of them! I’d also love to sing, and possibly be on Broadway. I want to do it all.”

But Maddie’s transition into acting isn’t the only big change in her life. Scroll through the gallery below to see pics of the brunette beauty with her boyfriend!
