Christina Aguilera wants to be 'rejuvenated'

Christina Aguilera wants to be 'rejuvenated' for her end-of-year plans.

The singer hasn't returned for the fourth season of 'The Voice' US and revealed last week she wants to get 're-inspired', before refusing to rule out new music in 2013.

Speaking at the screening premiere for the show's new series, she said: 'I'm going on vacation next week with my son, first time in Japan, which is such an inspirational place for me [to] get re-inspired, rejuvenated for what's to come... I can't say everything!'

Asked about the possibility of new music, she added: 'We'll see, yeah, if it feels right.'

The star's plans for a break with son Max, five, come after she advised teen star Justin Bieber to do the same thing after a recent disastrous week in the UK which saw the 'Believe' hitmaker collapse on stage and argue with paparazzi.

She explained: 'You live life and it's hard to grow up in front of a camera. You learn as you get older to take moments for yourself, step away from the camera, re-inspire yourself as an artist, rejuvenate and refresh.'
