Kim Kardashian says Kanye West likes her with no make-up on.

Despite being known for her glamorous style, the reality TV star - who gave birth to her first child last month - admits her rapper boyfriend favours a more natural look.

Kim, 32, said: ''He loves the dress up aspect, but he also likes me without make-up on.''

Meanwhile, her sister Kourtney, 29, admitted her husband Lamar Odom is a fan of a sexy red lip.

She joked: ''[He likes] lipstick, but he doesn't like to wear it second hand!''

Kim also shared her tips for faking razor-sharp cheek bones, revealing it's all down to crafty contouring.

She said: ''It's all about light and shadow; highlight your brow bones with a luminizer and very lightly enhance cheekbones with non-glittery bronzer.''

The Kardashian sisters - who have launched a new cosmetics line, Kardashian Beauty, available exclusively at Feelunique.com - haven't always looked so stylish and claim to have had their fair share of beauty disasters in the past.

Asked about their worst ever make-up moment, Kim confessed: ''Matching eye shadow to my hair accessories and clothes...''

Kourtney, 34, revealed: ''Too much make-up - pick a strong eye or a strong lip, not both!''

Several items from the Kardashian Beauty range sold out in a matter of hours on Monday night (15.07.13) on feelunique.com, with fans already on waiting lists to receive the Au Naturel Lip Kit Khloe Ultra Nude - In the Flesh and the Joystick Lip Stick Pen - Shocking Pink.
