The Emmy-nominated series began in 2015 and instantly proved to be a hit among comedy fans.
However, Netflix bosses have confirmed that the upcoming episodes will be the last.
Jane and her co-star Lily said they were both “delighted and heartbroken” when they found out the hit comedy was set for a return for its final season.
In the series, Jane portrays Grace, a cosmetics boss, while her real-life friend Lily plays Frankie, a quirky art teacher.
