The singer played a string of dates across the UK in support of his debut album Misty Eye and concluded the run at The Scala in London last night (October 2).
Grimshaw took to the stage to perform debut single 'Is This Love' as well as album track 'Hold On' and explained that the songs were about him being a "moody b**tard" after being eliminated from The X Factor.
London rapper Smiler joined the star on stage for their collaboration 'What We Gonna Be', while fans sang along to a rendition of album title cut 'Misty Eye'.
Grimshaw joked that he wanted to be "manly and write about money and guns and s**t", but ended up writing about his split from his ex-girlfriend instead.
The performer rounded off his set with a cover of Sia's 'Breathe', 'Nothing At All' and recent single 'Curtain Call'.
Taking to Twitter earlier today, Grimshaw said: "Pretty sad that it's over...Just sinking in as I lay watching Rambo that I've just done a tour! Hope you all enjoyed it as much as I did!"
Grimshaw recently explained that his debut record Misty Eye is "like a journal", adding: "I only understand it properly when I listen to the whole album."
