The 'Jealous' hitmaker was in a band with his older siblings Joe and Kevin throughout his younger years but admits there was "family issues that needed to be sorted out" towards the end.

In a docu-series posted on streaming service Tidal to promote the release of his upcoming album 'Last Year Was Complicated', he said: "It comes with layers of complication. I don't know how else to put it. I feel, among friends, uncomfortable speaking about it. It makes me feel like I'm complaining.

"Towards the end, there was just so much bias towards the brothers and the band. It's funny, it was meant to happen that it ended, but there were probably some family issues that needed to be sorted out ... At some point, I need to be able to look at it with a positive angle because it does suck that my 13 to 20-year-old years come with a lot of regret, almost, in a way."

Meanwhile, Nick previously admitted there was a time he felt under "pressure" to look perfect.

He said: "I never struggled with addiction on any level, which I think probably stems from living with diabetes. I'm not saying that I haven't had one too many drinks one night, but I think the thing that was most challenging for me was applying a lot of pressure to myself and trying to maintain a real image of perfection, which is so impossible. And we did have a lot of pressure on us to maintain that image.

"But once you become an adult you realise nobody's perfect, and it actually does you a disservice in your artistry to try and keep that up ... But it was more challenging than I've spoke about before."
