Who is the Cast of 'Sex Education' Dating in Real Life?

Asa Butterfield

In Sex Education, Otis, played by Asa Butterfield, is awkward and anxious when it comes to love. In real life, the actor mostly keeps his love life private, but he has been rumored to date a few different stars over the years.

Asa reportedly dated his Miss Peregrine’s Home for Peculiar Children costar, Ella Purnell, from 2015 to 2016.

Some Sex Education fans got excited in 2021 when they suspected a romantic connection between Asa and Mimi Keene, who plays one of his love interests on the show. The rumors surfaced after people online found Instagram photos posted by both stars where they appear to be at the same gorgeous buttercup field.

At the moment, Asa seems to be living the single life. When asked by GQ if he wanted to answer questions about his relationship status, the actor replied lightheartedly, “No, I want to keep them guessing.”

Gillian Anderson

Gillian Anderson plays Otis’ delightfully unconventional sex therapist mother, Jean Milburn. In the series, Jean falls for the charming Jakob after he does plumbing work in her house. Offscreen, Gillian appears to be single at the moment, but has had a variety of interesting romances over the years.

She split from her first husband, X-Files assistant art director Clyde Klotz, back in 1997. They share a daughter, Piper. In 2004, she married her second husband, British director and producer Julian Ozanne, and they split in 2006.

After her marriages, she dated Mark Griffiths from 2006 to 2015 and had two children with him: Oscar and Felix. She fell for British screenwriter and playwright Peter Morgan the following year. They worked together on the Netflix series The Crown and then had an amicable split in 2020 due to busy schedules.
