Get your tissues ready, 'cause the end is really here for "Pretty Little Liars." After seven seasons, it's #PLLGameOver on Tuesday, June 27, with a three-hour series finale event airing on Freeform.

The big farewell starts with the two-hour finale, "Till Death Do Us Part," from 8 to 10 p.m., followed by the "A-list wrap party," with stars Troian Bellisario, Ashley Benson, Lucy Hale, Shay Mitchell, and Sasha Pieterse joining executive producer I. Marlene King for an hour-long "unbarred and uncensored tell-all after-show to discuss all of the series' tightly held secrets, behind-the-scenes insights, and top moments."

Before all of that happens, fans can catch up with an all-day Season 7 marathon starting at 11 a.m., and running up to the start of the finale.

After last night's Episode 19, "Farewell, My Lovely," Freeform posted the big series finale promo, which promises "no more secrets" and "A.D. is revealed."Entertainment Weekly posted a page from the series finale script, if you want a sneak peek.

Fans are hoping for a perfect wrap-up, but PLL wouldn't be PLL if fans weren't left confused as hell, with still more questions hanging. It doesn't seem like there's a way to satisfy everyone, when there are so many competing theories out there about A.D. -- and everything else. But we'll see.
