One of Netflix's popular original movie franchises, The Kissing Booth, recently returned with a sequel that debuted on July 24. That won't be the last entry in the series, however, as it's been confirmed that a third Kissing Booth movie was filmed in secret alongside the sequel.

Deadline reports that The Kissing Booth 3 was secretly filmed concurrently with Kissing Booth 2 in South Africa. Filming is finished, and all that's left is post-production. The Kissing Booth 3 is expected to come to Netflix sometime in 2021, and bring back the stars of the original movies, Joey King, Jacob Elordi, and Joel Courtney. Additionally, director Vince Marcello, who directed the first two movies, came back.

The entire Kissing Booth series is based on the novels by Beth Reekles, the first of which she wrote when she was just 15 years old. Reekles said on Twitter, "It's been tough keeping this secret from you all but thank you for all the lovely messages."
