Some might consider this an unlikely duo but Celine Dion's ne-yo's duet is incredible, just that. A huge hit. They just shot the music video and now our Cameron Mathison goes behind the scenes for an exclusive look. Reporter: She's the vocal powerhouse with unmistakable pipes and he's the grammy award winning singer/songwriter behind some of radio's biggest hits and now these two voices are teaming up on an incredible duet call ed "Simply incredible" for Celine's "Love me back to life." The new single was written by ne-yo himself and I got an exclusive sneak peek inside the set of their video. ♪ Incredible ♪ Reporter: How did this collaboration come to be. I wrote some stuff for Celine on the album previous to this one. The issue for me initially was the whole concept of duet, you know, it's Celine Dion and ne-yo. My son, R.C. Who is going to be 13, the ne-yo, he said. He said, mom, you don't even have to listen to the song. You have to do it. What was it like doing it. Once I got over the initial shock of the whole duet scenario, you know, there were one or two takes where there was something I was looking for that wasn't there but in the back of my mind I'm like, do I critique Celine Dion. You can still at this point learn from other artist. Ne-yo among other artists gave me the chance to still be the best of myself with a little bit of tweaking the sound on a modern approach. Reporter: It may be a new mod determining sound for Celine but it's already poised to be another one of her unmistakable classics. We can expect to hear this during the olympics, right? I'm very excited about that because in the past I remember some athletes coming to me saying that, for example, "Love can move mountains" was their theme song and when I heard ne-yo's song for the first time, that piano line in saying -- ♪ the whole world is watching us now ♪ -- I said to myself this is my new olympic song now. Reporter: To my pleasure and delight I even got an impromptu concert. ♪ Since there's no way to calm down incredible ♪ ♪ oh oh oh ♪ Reporter: For "Good morning America," Cameron Mathison, ABC news, Los Angeles.
