Nicole Richie doesn't know how to put on her own make-up.

The reality TV star-turned-fashion designer star admits she is hopeless when it comes to styling herself and has to go to a salon every time she wants a red carpet look.

She told InStyle.com: "I actually don't know how to put on makeup - at all. I have to get it done every time I want to wear makeup. I do not know how to wear it at all. It's so bad."

As she can't apply it properly, Nicole, 30, doesn't even keep even most everyday make-up items in the house.

She added: "I don't even own it. I only own under-eye concealer, Maybelline mascara, and an eyelash curler."

While she may not be a whizz with a lipstick, Nicole is renowned for her great sense of style, which she admits she has inherited from her pop star father, Lionel.

She said: "When I was a little girl, my dad would have his costume designer that would make his tour outfits make me matching outfits out of the excess fabric.

"For whatever crazy rhinestone bell bottom outfit hat my dad was wearing with his big Afro, she would make me a dress out of it."

Nicole also runs two of her own fashion lines, House of Harlow 1960 and Winter Kate.
