Britney Spears suffers from obsessive compulsive disorder.
The pop singer, who is pregnant with her second child with husband Kevin Federline, says she can't stop cleaning and scrubbing her home because she is convinced it is always dirty.
She revealed: "Fans don't realise I have an obsessive compulsive disorder. It's true."
Earlier this week, Britney confessed she has become paranoid about her mothering skills.
The 'Toxic' singer admitted she frets around son Sean Preston after being publicly criticised about her parenting on several occasions.
She said: "To sum it all up - being a mum is one of the most scary things there is. I didn't want to respond to a lot of things people have been saying because it has been rubbish."
