Kim Kardashian `said no to endorsing butt enhancement pills`

Appearing on the Rachael Ray Show with mum and manager Kris Jenner, she said that she is asked to endorse all kinds of products, but drew the line at the pills which claim to give you a bigger behind.

'I have said no to butt enhancement pills!' she said. 'I'm like, I don't think I need them and this is just crazy. I would never endorse a product like that!'

Her mum added that she always lets Kim know what companies offer, whatever the product.

'It's my job as a manager to present them with every single deal, whether I want to or not,' she said. 'It's nothing about the 10 per cent, I swear.'

The Kardashian family netted $65 million in 2010, and Kris said plans are underway to bring her youngest daughters Kylie, 13, and Kendall, 15, into the picture.

'We've been batting that around a little bit,' she said. 'As long as they get good grades and they keep doing what they're doing and they're good girls.'
