Kim Kardashian's natural beauty:  Kim Kardashian says her absolute beauty must-have is concealer. The 29-year-old reality television star always looks glamorous on the red carpet, and her immaculate appearance means she is often voted one of Hollywood's sexiest women by men's magazines.

To achieve her flawless look, the raven-haired beauty says she wears plenty of make-up, and admits she couldn't live without her concealer.

"I love mascara. And I always have dark circles under my eyes, so concealer is a must. I always have blusher in my bag too. Your face looks cuter a little flushed," she explained in an interview with More! magazine.

Despite her reputation for following a high-maintenance beauty regime, Kim is still happy to leave the house without applying any cosmetics. The star says that when she does, she always makes sure she has her signature shades with her as they hide a multitude of sins.

"But I do go out without any on sometimes. I mean, that's what big sunglasses are for! I never leave home without my giant sunglasses. If you see me wearing them in pics, it usually means I don't have any make-up on underneath..." she revealed.
