A lipstick chosen by Natalie Portman for Dior will give its proceeds to the Free the Child Foundation.

The Oscar-winning actress - who is the face of Miss Dior fragrance and Diorskin Nude foundation - is an ambassador for the charity, which helps liberate children from poverty, and chose it to receive money made from the sale of Rouge Dior's Nude Grege lipstick.

She revealed she picked the shade due to its number 169 having a special meaning to her: "Six is the month that my whole family was born in -- everyone was born in June. We're all June babies. Nine is a magic number, and one is my son - his name is one in Hebrew, Aleph."

Natalie - who is married to ballet dancer Benjamin Millepied - has a long history with Dior, and recently auctioned off a vintage 1954 dress by the house she wore to the Oscars this year.
