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.’
