Friends of Christina Aguilera are 'fed up' with her wild behaviour.
According to US Weekly the tipping point came when she took her new boyfriend Matthew Rutler into the bathroom at a recent family gathering.
A source said: 'Her friends are fed up.
'Nobody can get through to her. They think she's trashy and her ego is out of control.'
Another source added: 'She's really spiralling. I would be shocked if she's not in rehab in the next month or two.'
