Which song has Justin Timberlake finally denied was written about ex-girlfriend Britney Spears?

Justin Timberlake has finally denied What Goes Around... Comes Around was written about Britney Spears.

The 45-year-old singer released the track in 2006 and many fans speculated it had been inspired by his 2002 break-up from the Toxic singer - who was divorcing Kevin Federline at the time - back in 2002, but he's now explained he wrote the song after talking to a friend about their own relationship breakdown.

Speaking on Complex's Re-Rank YouTube series, he said: “Maybe I should dispel a rumour at this point, which has gone around forever, which is like, it’s not a personal story from mine.

“It’s actually a personal story from a friend’s that I asked permission [to use].

“He was just going through [a break-up] and he was telling me what had happened, and I said, ‘Do you mind if I write about this?’ And I quote, my friend said, ‘Yeah, torch that b****. What goes around comes around.’ And I was like, ‘I have to go. Thank you.'"
