Justin Timberlake just released his new album, 20/20 Experience and is gearing up for the November release of part two of the soulful smash that featured "Suit and Tie" and "Mirrors". Not only is Timberlake planning on using unused tracks from 20/20 Experience, but he also plans on writing new material.

Timbaland collaborator Jerome "J-Rock" Harmon revealed some info on the 20/20 Experience follow up.

"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."

The 20/20 Experience producer also revealed that Timberlake's second single, "Mirrors" was written and recorded a long time ago; JT just kept it on the back burner.

"'Mirrors' was something we started working on in 2009 and he just shelved it," Jerome teased. "He's like, 'I'm gonna save this one, and this is gonna go on my album'.

"We never knew when he was going to put it out, we could have waited another 10, 15 years," Harmon recalled. "But then he surprised us last year and said he was ready and he brought 'Mirrors' over to the project as well."

Justin Timberlake and Jay-Z will kick off their "Legends of the Summer" summer tour July 17 in Toronto.
