Fern Britton has revealed that taking a Mensa test led to her divorcing her first husband.
The TV presenter, 64, admits that her passing the test when ex-hubby Clive Jones didn't caused a rift in their relationship.
The IQ test allows people to join the High IQ Society if they score in the top two per cent of the population and Clive - who Fern shares three children with - was less than impressed that she secretly took part.
