The SexyBack singer has recently taken a break from music to concentrate on his acting career with roles in films such as Bad Teacher and Friends With Benefits.
And although Justin hasn't given up on music just yet, he says he can't imagine touring for much longer since turning 30 back in January.
Asked whether he plans to release another album soon, Timberlake told Vanity Fair magazine: 'I really just don't know. I wouldn't say I'm not going to put out another one. I would say that would be a bad bet, if you were betting. But I could see myself only doing one more big tour.'
The star is currently enjoying having some time off work.
He added: 'Right now, I'm not in the mood to work. I want to not have a schedule. I want to go to the Dodgers game if I feel like it. 'Hey, do you guys want to play basketball today? Cool, let's do that.' I've never really given myself the opportunity to be spontaneous.
'I figure I can go on like this until the end of the year. I don't have anything I have to do. The only job I have to do is promote the films that are coming out.'
