Singer has been celibate for months
Britney Spears admitted on TV earlier this week that she hates the constraints put on her life.
The singer’s father Jamie is in charge of her estate, finances and well-being and closely monitors everything she does.
But in private the 27-year-old singer has also complained about her lack of a sex life.
‘She has been celibate for months now and jokes to friends she may as well be a nun,’ a source says.
‘The constraints on her life are totally suffocating. She has been crying in private and putting on a brave face in public.’
Britney, 27, is also thought to have been put on a strict eating plan ahead of her world tour next year.
‘Every mouthful is being monitored,’ the source tells the Daily Express. ‘She’s on a strict no-sugar diet.’
