Justin Timberlake already planning new album

The pop star made his return to music earlier this year with his third studio record - which has already become the best-selling album of 2013 so far - and plans to revamp the unused tracks for his next LP, scheduled to be released in November.

Producer/songwriter Jerome 'J-Roc' Harmon, who has worked with the singer on several occasions said: "Before we came to the 10 [songs on The 20/20 Experience] that he wanted and the two bonus tracks, we had over 30, 40 tracks.

"So I think he's going to go in, and we're going to take some of the stuff that we've already done, and of course create more music at the same time."
