"How Can I Forget" is a single by American pop duo MKTO, released on August 22, 2018.
The song is about being unable to forget about one's partner in a previous relationship. Malcolm David Kelley stated that he "jumped in and out of a relationship" at the time he started the song. According to Tony Oller, the support they have received from fans and emotional connections formed with them also served as inspiration for the song. The song was written during MKTO's brief hiatus in 2017, and also as an ode to the fans who have not forgotten about them.
The music video was directed by Izak Rappaport and released on September 7, 2018. It was inspired by Westworld and filmed at Point Dume in Malibu, California. It sees MKTO hooked up to machines that trigger memories from past relationships, and hanging out with their respective girlfriends at the beach.
