Obsessive compulsive disorder - or OCD - appears to be the trendiest affliction you can claim to have.
The psychological condition can be devastating, causing unpleasant, anxiety-inducing thoughts as well as repetitive behaviours and obsessive habits, such as repeatedly washing your hands or checking that doors and windows are locked.
Celebrities, of course, are not immune to mental health problems and some genuinely suffer from the disorder - but many others admit to 'self-diagnosing' and speak of this distressing affliction so flippantly that it sounds as if they're simply talking about the latest fad diet.
. Here FEMAIL examines some of stars who say that they suffer from it - and while you will sympathise with some, you won't with others

Bra tycoon Baroness Mone controversially claimed in a TV interview last month that OCD 'helped her get ahead'.

His wife Victoria added: 'He's got that obsessive compulsive thing where everything has to match. If you open our fridge, it's all co-ordinated down either side. We've got three fridges - food in one, salad in another and drinks in the third.
