After seven jaw-dropping seasons, Pretty Little Liars is coming to an end. The series finale airs on Tuesday night, and the cast took to Instagram to bid their farewells. Troian Bellisario shared a series of snaps with her costars in an Instagram album and reflected on what it was like playing Spencer Hastings for eight years. "Every moment with this cast and crew, in this town, every breath I took with Spencer, every text, dead body, new suspect, terrifying scream, new relationship and 'kisses, A;' taught me something extraordinary," she wrote. Ashley Benson posted a photo of her and the ladies watching fan videos on the last day of filming, while Sasha Pieterse looked back on her "incredible journey." "I am so ridiculously grateful to each and every one of them. To our amazing fans I am most definitely forever grateful," she captioned a black-and-white snap of her and the girls. Cue the waterworks!
