"It's going to be a banger bop, everyone's going to love it and [Radio 1 is] going to play it three billion times."
The pair struck up a close friendship after their success at the 2020 Grammys and even went out celebrating at a strip club together.
When asked what his highlight of the prestigious awards ceremony was, he previously spilled: "Probably when I went to the strip club with Lizzo. That was a pretty great time. They were playing our songs and stripping. It was a crazy night."
