The 29-year-old is having second thoughts after seeing how tough her sister Kourtney finds bringing up her 10-month-old son Mason.

“I’ve always wanted a big family. But seeing how much hard work brining up Mason is for Kourt has given me a reality check. I don’t think I’ll be rushing into that just yet,” femalefirst quoted her as saying.

The 29-year-old reality TV star who first became famous because of a leaked sex tape, seemed to take inspiration from the infamous home video for the advertisement, reported E! Online. The socialite stars in an advertisement for American fast food chain Carl’s Jr. and manages to turn eating a salad into a highly sensual experience.

Kardashian appears naked in the bath, apart from some strategically placed bubbles, in one scene while in the other she is seen writing around on a bed, eating a salad wearing nothing but a cream coloured robe. The second of the three Kardashian sisters, Kim has recently been on a health kick herself, slimming down after a magazine in the US released a photo of her that had not been retouched, exposing her cellulite. ‘Complex’ magazine mistakenly posted the wrong picture of the star, one that hadn’t been touched up by the airbrush.
