Sex Education star Asa Butterfield, who plays Otis Milburn on the show, has confirmed that season four of the popular Netflix show is now in production.
The actor posted a picture on Twitter of himself from outside of his trailer as he sipped something from a mug, with the caption: "Guess who's back?"
His co-star, Alistair Petrie, replied with another hint: "Give us a clue."

Sex Education has been marred with news of a series of cast members leaving the show for a myriad of reasons. Bridgerton's Simone Ashley, Patricia Allison, Tanya Reynolds and many more actors have explicitly stated that they will not be returning to the fan-favourite Netflix show.
Tanya Reynolds also recently spoke exclusively to Digital Spy about how season four of Sex Education might be the show's last.
"I think it's that thing when you're playing teenagers, and the whole the root of the show is in a particular environment like a school,” she said. "You have to age, you have to move on, so there is always an end in sight."

"It's not like Friends for example, where it's just following these people as they grow up and in their lives, because this is in an institution."
While some cast may be leaving, there will be still some of Moordale Secondary School's most beloved students sticking around.
Ncuti Gatwa was recently confirmed to be returning as Eric even though he is due to star in Doctor Who's 60th anniversary in the coming months.
