Lana Parrilla, who plays the Evil Queen in the series 'Once Upon a Time,' shared an endearing message with her fans via Instagram. As the show's finale is set to air on May 18, the star reflected on the past seven years.

Sharing a photo of her in costume, Parrilla wrote, "Dear #onceuponatime fans, I would like to thank you all for your love and support over the last 7 years! I never could’ve imagined I would get to play an iconic Disney character in my career and who better than the Evil Queen herself! ONCE’s EQ Regina Mills was so much more than a villain. She became a hero, an inspiration and one of the most influential characters on the show. She became MY hero. I learned so much from her and I will miss walking in her shoes. I am eternally grateful for the opportunity I’ve had to play Regina. Thank you, thank you, thank you @adamhorowitzla @edwardkitsis @disney & @abcnetwork. This experience has changed my life! Everyone please enjoy tonight’s series finale of Once Upon A Time! It’s a tearjerker so prepare yourselves! All my love - Lana"

Promising to be an emotional episode, the series finale of 'Once Upon a Time' will pay homage to the classic Disney adventures as well as the creators' original vision for the show. Watch 'Once Upon a Time' on Friday, May 18 at 8/7c on ABC.
