Christina Aguilera and husband Jordan Bratman are believed to have separated.
Christina, 29, and her music executive spouse, 33, met in 2002 and married in November 2005
'They are now living apart, and they will see how that goes,' a source tells Us Weekly.
'They were very much in love. But over the last six months, it became clear they were more like friends than husband and wife.'
The couple are parents to son Max Liron, 2, and Christina has previously revealed she's been asked to tone down her sexy image since becoming a mum.
'I've had people say I shouldn't sing songs about sex when I'm a mother,' she's admitted.
'But I wouldn't even have Max if it wasn't for the act itself.
'Jordan started dating me on the set of my Dirrrty video, so he knew what he was getting into.'
Christina's spokesperson says she has no comment at this time.
