"Dance Moms" star Maddie Ziegler appeared in the latest "Pretty Little Liars" season 6 episode titled "She's No Angel." It was said that the executive producers have long wanted Ziegler to guest on the ABC Family series.
In an interview with Entertainment Weekly, "PLL" executive producer Oliver Goldstick shared that the reality star have long expressed her interest in being part of the series. Ziegler said that she is a huge fan of the Liars and wanted to meet Lucy Hale (Aria), Ashley Benson (Hanna), Troian Bellisario (Spencer), Shay Mitchell (Emily) and Sasha Pieterse (Alison) in person.
The showrunner said that they have wanted to guest Ziegler since season 5, however, they have just finished another dance sequence with Mitchell and Benson. The writers thought that adding another one would be overkill.
When they finally find the perfect storyline to add the reality star, they reportedly sought assistance from Travis Wall of "So You Think You Can Dance." According to Inquistr, Goldstick was very specific with how he wanted the choreography to end up. He wanted the sequence to be haunting yet it should not be similar to the "Exorcist." They were also very particular with their choice of music. Goldstick and Wall had decided that they wanted a gentle and delicate melody to give emphasis to Ziegler's performance.
When asked how Ziegler is related to the "A" storyline, Goldstick speculated that she could be one of the Allison girls that s/he has kidnapped. He said that this particular dance scene was one of the most disturbing scenes ever filmed for "Pretty Little Liars."
