'Pretty Little Liars' season 7 spoilers: Torrey DeVitto wraps final scene; Keegan Allen bids Troian Bellisario goodbye

Torrey DeVitto has filmed her final scene in "Pretty Little Liars" season 7.

The actress announced that she is officially done with the Freeform teen drama on Thursday, Oct. 20, just days after news broke of her return in the second half of the show's seventh and final season.

DeVitto plays Melissa Hastings on the series since it premiered back in 2010. She played the role in a recurring capacity in the first three seasons before retuning as a guest in seasons four and six. Melissa is the older sister of Spencer Hastings (Troian Bellisario) and has been engaged to Wren Kingston (Julian Morris) for most of the series. She was revealed to be the Black Swan and the Queen of Hearts in seasons 2 and 3.

The last time Melissa was seen in "Pretty Little Liars," she had flown back to England and was seeing Wren again.

"In the wee hours of this morning I did my final scenes as Melissa Hastings," DeVitto wrote in an Instagram post. "So much has happened over these last 7 years, but through all these changes, 'Pretty Little Liars' stood as a constant space to go back to," she continued.

DeVitto expressed gratitude for everyone who has worked on and watched the show, adding, "It's been such an honor to play this character and work with such an amazing cast and crew."

She later posted a photo of herself with Bellisario, her on-screen sister, calling her co-star "the best tv sister a girl could have."

Bellisario was in another farewell post, this one by her "Pretty Little Liars" co-star Keegan Allen, who plays her love interest Toby Cavanaugh.

Allen recently Instagrammed a photo of Bellisario in which he announced their "last hours" as Spencer and Toby.

"I have grown up with you and learned so much from you," he wrote. "I'm a better person because of you... I absolutely love you Troian Bellisario," he added.

"Pretty Little Liars" season 7 returns in April 2017 on Freeform.
