The pair have teamed up for their new track 'Up', which features on Morrison's recent chart-topping album The Awakening.
The video sees the duo in an old London town building performing the track while seated back to back.
They then move on to the building's roof and are surrounded by views of the UK capital for the ending of the guitar-driven ballad.
Morrison recently told Digital Spy of working with the 'Who You Are' star: "[It was] pretty intense. I was s**ting myself to be honest! She's sassy and an amazing popstar.
"She doesn't normally record tracks that she hasn't written herself, so I felt pretty privileged that she agreed to do it."
'Up' is the second single to be lifted from Morrison's The Awakening and follows his recent cut 'I Won't Let You Go'.
