The actor and former So Solid Crew rapper has teamed up with the Britain's Got Talent judge for 'Your Love', which is available to download from October 14 via SK Records.
"I am really excited to be working with Alesha," Walters said of the track. "We had fun creating the track in the studio.
"She has a great voice and brings a different vibe. I wanted us to create something very distinct from my previous work."
Discussing his influences, he explained: "I always try to write from my own personal experiences and this track reflects events in my journey. It's about change and moving forward positively. I hope you like it!"
The pair filmed the song's accompanying music video in London's Jazz Cafe, which was shot in 16 hours. Two behind-the-scenes pictures from the shoot appear below:
