The 32-year-old reality TV star admitted that although her rapper boyfriend appreciates her glamorous look, he also likes her 'au naturel'.

In an interview with beauty website Feel Unique she said: "He loves the dress up aspect, but he also likes me without make-up on."

Kim’s younger sister Khloe also revealed her husband Lamar Odon’s make-up preferences.

"[He likes] lipstick,” she said, “but he doesn't like to wear it second hand!''

Kim also explained that her much coveted make-up look is down to clever 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 have recently launched their own cosmetics line, Kardashian Beauty, however they haven’t always been make-up pros.

According to Kim, her biggest make-up mistake was "matching eye shadow to [her] hair, accessories and clothes."  

Whereas her older sister Kourtney said her worst make-up mishap was "Too much make-up – pick a strong eye or a strong lip, not both!"
