The star is set to reunite with cast mates Ashley Benson, Troian Bellisario, Tyler Blackburn, Ian Harding, Shay Mitchell, Janel Parrish, and Sasha Pieterse for an upcoming Covid-19 fundraising livestream for non-profit Feeding America on Friday, May 15, 2020.
In a chat with Entertainment Tonight, Lucy said the virtual gathering was "a no-brainer," as all of the stars have plenty of free time while stuck in lockdown, and she went on to muse over the future of the franchise - which she's sure will be revived.
"We're in a quarantine that we thought would last a couple weeks. Anything is possible at this point," she said of a potential big screen project. "I don't rule anything out, (but) I feel like we'd need a little more time to pass. I feel like we would get more out of it if we were, like, 10 years down the road."
Lucy continued, "I feel like they're gonna do a spinoff or something before then. I don't know. I'm so protective of this show So I feel like when the time comes that they want to do it with a whole new cast, I might have to produce it because I'm way too protective of it."
The actress played Aria Montgomery in the teen drama series, about a group of friends being stalked by a mysterious figure named "A" who threatens to expose their deepest secrets.
The "Pretty Little Liars" reunion event, hosted through Cast4Good, kicks off Friday at 3 P.M. ET. Check out the stream here.
