The actor hinted at a massive storyline on the way for Nick during a live TV interview on This Morning today (December 17).

Nick is due to marry his fiancée Leanne Barlow (Jane Danson) on Christmas Day, with uncertainty surrounding whether the ceremony will actually go ahead due to Leanne's unresolved feelings for ex-husband Peter.
However, Price revealed that the biggest shock in store for Nick is separate from the ongoing love triangle.
Discussing what he is filming at the moment, the actor explained: "I'm quite a way ahead - I'm into February now, March. I finish on Friday, we get two weeks off [for Christmas] and the studio stops, which is great. Then we come back and you're a bit more energised.
"But the story moves on so quickly in Corrie. Now I'm dealing with a whole different kind of mess. Peter's sort of gone to the side, and I'm dealing in something very, very big. Huge, really big!
"[It] happens on Christmas Day apart from the wedding. It will ripple through his life for the rest of time - and the Platts'!"
Describing the storyline as an "amazing twist", he continued: "This is what's great about Corrie - you can play these big, big stories so quickly. The audience think, 'Well, I've got you in a box' - but no, no, you haven't. You're going to see Nick lose that veneer he's had for so long, I think."
Coronation Street airs an hour-long episode on Christmas Day from 7.30pm on ITV1.
