The one off hour special will air at 6PM on April, 16 on ITV.
The episode will recap Mo's story from his first blind audition to being crowned the winner, and his work on his winner's EP which is expected to be out the same weekend.
"They are filming my winner's documentary as we speak right now!" Mo said this week. "It’s not too weird as I’ve been on a TV show for a few months now – another week of cameras won’t hurt me.
"I believe the show is mainly going to be about the journey from winning The Voice to recording and release the EP, and then what’s next. I’m looking forward to it."
And Mo has big ambitions for his debut EP and full album, which will follow later.
"I've been writing songs for years and music has always been my passion – it’s been an essential part of my life since I was a kid," Mo explained this week. "I want to be able to write and get my thoughts and feelings out to people in a positive, constructive way.
"I will definitely be writing songs and I’m planning to collaborate with other writers as well. Two hands are better than one, as they say."
Speaking to the Official Charts website, Mo went on: "Sound-wise, I’m not going for any one particular vibe, genre or style. For me, I tend to go for the feeling or the emotion that I want to give out. Sticking to one genre can limit your creativity and I think that could get a bit tedious and boring over time. I don’t want to pigeonhole myself."
