Joan Rivers takes naked photos of her daughter in the shower

Joan was frustrated that her daughter did not instantly snap up a big-money offer to pose naked for Girls Gone Wild mogul Joe Francis.

Joan was then seen sneaking into the bathroom and taking photos as her shocked daughter screamed and tried to cover up in the footage shown on their new reality TV show, Joan & Melissa: Joan Knows Best?

Insisting her daughter has an 'amazing body', Joan says she will live to regret not taking up the offer when she gets as old as she is. 'My breasts - I could nurse China from my bedroom. It's all over,' she quipped.

In a meeting with Francis, Melissa was stunned when the X-rated businessman showed her a mocked-up DVD cover for Hollywood Mum's Gone Wild as well as a magazine, both with her on it. Joan, however, said: 'I would just be so proud to say, 'You see that slut on the cover? That's my daughter'.'

'I can't do it,' Melissa later told Joe. 'I'm not gonna lie, Joe's offer was incredibly tempting - it was a lot of money - but in the end I'm a mom and I have to think of what's best for my son Cooper.'
