Former glamour model Jodie was shocked when she heard this asking: 'So some have used a surrogate then stuffed a pillow up their jumper?'
'We are talking about well-known women,' Dr Sahakian confirmed. 'It would be taboo for them to admit they used a social surrogate. I have had a couple of patients who pretended they were pregnant, yes.'
A number of A-list celebrities, such as Nicole Kidman and Sarah Jessica Parker, have been vocal about their use of surrogates in their 40s because they were not medically able to carry their own child.
Dr Sahakian said his 'social surrogate' clients are typically younger and know from an early age that they want to be mothers. They don't want to delay motherhood till their late thirties and early forties in case it means they have left it too late. But they also don't want to 'ruin' their bodies in their twenties when their career could be at its peak.
But Dr Sahakian said he can understand why some women see it as an attractive option.
'Who cares what people think? Do what is best for you,' he said.
