After divorcing her husband three years ago, Pauline Potter - already a whopping 46stone - piled on so much extra weight that she became the heaviest woman in the world.

But at a staggering 50stone, her ex-husband Alex (a svelte 11stone), couldn't resist her and set out to win her back and reignite their sex life.

The couple now have marathon sex sessions of up to seven times in one day and Pauline maintains that the 'sexercise' is what's keeping her slim.

The 'sexathons' with Alex, who has visited her twice a month for four days at a time, have had a dramatic effect on her size, helping her shed a stone each month by sweating off the calories.

'I can't move much in bed, but I burn 500 calories a session-it's great exercise just jiggling around,' she told Closer Magazine.

Even though one of Pauline's legs weighs more than Alex does, the couple are able to enjoy sex using different positions.

And although Pauline isn't yet confident enough to buy sexy lingerie, she drapes a nice sheet over her to achieve the same effect in the bedroom.

The 47-year-old, who as a 19-year-old son Dillion from a previous marriage, met Alex in 2002 online and they married three years later. READ MORE HERE
