"Overthinking" follows Mabel's March single "Good Luck", and sees her link up with 24kGoldn for the first time since featuring on Clean Bandit's "Tick Tock" in August 2020.
The new track, produced by Stargate (Rihanna, Katy Perry), is teamed with a Charlie Sarsfield-directed video.
Mabel explains that the new outing is "about how quickly things can turn from thrilling to toxic. Many people suffering from mental health disorders self-medicate and I too went through a time when I turned to drugs to numb my feelings. I hope that anyone that may resonate with this song knows that after the darkness comes the light."
She's yet to follow up her 2019 debut album High Expectations.
