Justin Timberlake has revealed the follow-up album to The 20/20 Experience will be "hotter, older and evil".
The Grammy-winning pop star, who will release The 20/20 Experience 2 Of 2 on September 30, said that the second part is like the "hotter, older, evil twin sister" of the first edition.
"If you could imagine you're 16 and she's everything you thought. She's Marilyn Monroe and then you meet her older sister; everything that's dark and wrong about her at that age is why you become infatuated with her," he told the New York Times.
Justin's performance at the iTunes Festival on September 29 will coincide with the album's release a day later. Take Back The Night is the lead single from the album.
The 32-year-old - who will be back on the big screen in thriller Runner, Runner and the Coen brothers' musical biopic Inside Llewyn Davis - said he doesn't worry about success and failure.
"You get to this point, which I've done in the last five or six years, where you become less worried about success and failure," he said.
"If you can answer the question of why you're doing it, it's the right thing to do. To answer the question 'Why?' for the first time in my career, is: because I wanted to."
