The girls of Pretty Little Liars are just as close off camera as they are on.

Series star Shay Mitchell, 25, opened up about the cast's tight bond during a recent interview with Us Weekly's This Minute. "It's so much fun going to work! It's like a slumber party on set, especially those night shoots," Mitchell told Us. "And Ashley [Benson] lives close to me, so she's always over at my house for girl time. I love baking."

And Mitchell, who is also an American Eagle spokeswoman, has a big sweet tooth. "I'll never turn down a red velvet cupcake," she admits. Still, the Toronto native is focused on her fitness. "I love working out. Dance classes are my favorite."

Though her costars are all attached, Mitchell insisted she's "pretty happy" being on her own. (Benson, 22, is dating TV producer and "swagger coach" Ryan Good, 32; Lucy Hale, 23, is dating American Horror Story actor Chris Zylka, 27; and Troian Bellisario, 26, is dating Suits star Patrick J. Adams, 31.)

"Being single is not as bad as everyone likes to make it seem!" Mitchell assured Us.
