Pretty Little Liars' Lucy Hale has some advice for reboot cast

Pretty Little Liars came to an end four years ago, but as we've come to expect these days, a reboot of the teen drama is already well under way.

The revival, which will air on HBO Max in the US, will go by the new name of Original Sin – and along with a new home and a new title, it's set to introduce a whole new cast.

Lucy Hale, who played Aria Montgomery in Roberto Aguirre-Sacasa's series, has now offered the new secret-keepers some sweet advice as they embark on re-imagining PLL for a new generation.

"Oh my god, it's so depressing that I already have to give advice to a new generation," she joked to TVLine recently. "But I think it's great. It's an honour that they want to continue the legacy of Pretty Little Liars."

Offering a pearl of wisdom to the new cast, Hale advised her successors to "enjoy" the moment and not get too caught up in the future.

"I have a feeling their lives are about to drastically change, like ours did. When I was doing Pretty Little Liars, I was always thinking about the next year," the actress explained.

"I was never in the moment, so I missed a lot of the little moments. We were worrying about things we shouldn't be worrying about. It's very vague, but my advice is just to enjoy it."

Sharing her support for Original Sin, Lucy added: "It's a once-in-a-lifetime experience. People are going to love you guys, and I'm definitely going to be watching. All the love to everyone involved."
