The Xtra Factor presenter and former contestant confessed that it was "brilliant" to take the stage again on the show.
"It was great to go back and see the judges again and have a laugh," he told Capital FM.
"The thing about it is, when you're a presenter and on the show, you're literally on it every week - you do just want to go down and perform.
"Obviously I'm a singer in my own right and you see all these contestants performing - it's like, I want to showcase what I can do and I think it was a great way for me to do that at the weekend and I was so excited."
The 'Troublemaker' singer is on the path to scoring a number one with his new single this weekend after beating Girls Aloud's 'Something New' in the midweek charts.
