Finally, the final season premiere of Pretty Little Liars has arrived and the feelings are bittersweet.

Ahead of the season premiere, fans still have a lot of unanswered questions.

Besides the fact that we still don't know who A.D. is, Liars lovers still don't know who shot Spencer at the end of the summer finale and whose baby Ali is currently pregnant with. These are just some of the things floating around our heads.

There's a chance that all of the questions will be answered throughout the course of season 7 but leave it up to Marlene King and the rest of the Liars' writers, directors, and producers to leave us hanging at the end. But, the excitement is building and that's not just with the fans. The actresses who the world has come to know and love are gearing up for tonight's premiere as well.

The girls are busy in the big apple doing some promo for the final season and they are having tons of fun at the same time. Shay Mitchell shared this video clip on Instagram with the caption, "Always so much fun when we're together!!! #PLL #PLLtheLASTseason ! Thanks @facebook for having us! ?."

It's clear that these girls are a family and just because tonight is the beginning of the end of Pretty Little Liars doesn't mean they will be leaving each other in real life. This is a show that has brought them together like nothing else had ever done before. It's a connection that no one else can completely relate to.

The season premiere should be exciting and we're already at the edge of our seats thinking about what questions will be answered!
