Payne signed a solo record deal with Capitol back in July.
On Thursday, October 6, he shared on Instagram a photo of him and Pharrell in the recording studio, reported Aceshowbiz.
The 23-year-old singer wore an all-black outfit consisting of a hat, an Adidas hoodie, sweatpants and sneakers. The "Happy" hitmaker, meanwhile, sported a grey hat and sweatshirt paired with ripped denim shorts and pink boots.
"Great few days with @pharrell pleasure working with you as always," Liam wrote along with loads of exclamation mark and fire emojis.
