We know it's hard to believe, but Justin Timberlake apparently knew nothing about the Eurovision Song Contest – until he turned up to perform at least.
Appearing on tonight's episode of The Graham Norton Show, JT revealed that he actually said yes to performing at the contest before knowing anything about the iconic event. Sacrilegious.
"I did, but not before I said yes to it," he admitted. "Then, when I told people I was doing it they would respond with, 'Oh, why are you doing that show?'
"I thought, 'Why not, a lot of people watch it!' It was a lot of fun."

Although we're not quite sure how you can spend 35 years on this earth without experiencing the joy that is Eurovision, we're glad enjoyed his time there.

Taking to the stage at the show's halfway point, Justin performed a jazzed-up version of that '00s classic 'Rock Your Body' as well as his new single (for new movie Trolls) 'Can't Stop The Feeling!'.
Justin has been getting comfortable on Graham's sofa to promote his upcoming animated comedy Trolls alongside Anna Kendrick.
Calling his role as main character Branch his "dream job", the 'Trousersnake' also admitted the inspiration behind the film's lead track: his son. Bless.
"'Can't Stop The Feeling' was meant as a celebration but I wouldn't have written it that way if it wasn't for him," he said.

You can catch it on BBC One tonight (September 30) at 10.35pm.
