In the teaser trailer, t looks like the Derry Girls gang - Erin, Clare, Michelle, Orla, and the wee English fella James - are still up to their old tricks in the quick clip that sees police descending upon the group.

“This is a setup!,” Erin Quinn, played by Saoirse-Monica Jackson, shouts at the police in the teaser.

“You have my full cooperation, sir!” a near-hysterical Clare Devlin, played by Nicola Coughlan, shrieks.

Lisa McGee, herself a native of Derry and the creator of the beloved series, shared a selfie with the caption "last day of school."

Channel 4 says Derry Girls is the creation of acclaimed writer Lisa McGee who has mined her own experiences to create a candid, one-of-a-kind, family-centered comedy.

While series one saw the gang navigating their teens in 1990s Derry against a backdrop of The Troubles, series two saw them navigating their parents, parties, love interests, and school against the backdrop of a precarious peace process. Northern Ireland is growing up - this gang of eejits certainly aren't anytime soon.

We can't wait to see what series three, which airs in 2022, though we'll be sad to see the show come to an end!
