The singer admitted that the songs on his debut LP Misty Eye are about what happened to him after a relationship ended badly.
Discussing the record with Digital Spy, he said: "Intense is a good word for it, I suppose. The album forms a vague narrative around a breakup.
"Most of the songs were written after a bad breakup and when I was drunk. It's a feel-good album though - it questions your intensity and anger. There are definitely some feel-good vibes on there as well."
Grimshaw also admitted that he has spent the majority of his time since finishing ninth on The X Factor in 2010 "bonding with the sofa", adding: "I've mainly been watching One Direction taking over the world from my sofa."
The star's new single 'Is This Love' is out June 3. Watch the official music video below:
