Justin Timberlake Rules Out X Factor Judging Role
JT also defends the length of new single Mirrors...
"And it's obvious when someone's not good. But I just don't have the heart [to do it]."
In the same interview, Timberlake also defended the making of long tracks, after his new single Mirrors totalled at over eight minutes long.
The song is currently sitting pretty at the top of this week's iTunes chart, and if it retains its position, it could be one of the longest No.1 singles ever.
Jumping to his own defence, the 32-year old told the radio station: "When we were making the record I said, 'If Pink Floyd and Led Zeppelin can do 10-minute songs and Queen can do 10-minute songs then why can't we?' We'll figure out the radio edits later.''
The former NSYNC star also hit the headlines this week after confirming he's worked with Marcus Mumford on a song for new movie Inside Llewyn Davis - which Justin stars in alongside the folk singer's wife, Carey Mulligan.
