But despite facing the end of their long-term relationship, Nick insists there are no hard feelings between them.
'I have all the love and respect in the world for Olivia and the ride we had together. It's just the right thing for me to be on my own,' he says.
'I feel really good. It's been an incredibly crazy year and a half of my life so I'm enjoying just being a solo person.'
Luckily for Nick, close pal Taylor Swift has been on hand to advise about matters of the heart.
'She's a very good friend with a lot of good opinions and an awareness of how things work, which is helpful. It's always good to get a girl's perspective,' he says.
'There's a strange mentality of celebration that goes into that when you're a male pop musician. I just feel for her [Olivia] in those cases.
'There's not really a lot of sensitivity. With social media people don't realise that you might see it. They think it'll just end up in the abyss of your mentions but you actually do see things.
'But I get their passion on both ends.'
