Inés's riddle

Here it goes:

I'm thinking about a woman who was born in 1929 in Belgium.

Douring her life she worked as a model, as a singer , as a dancer and as an actress.

She first starred in british films but soon she got her first leading role in a Hollywood movie called Roman Holidays and soon followed leading roles in films such as Breakfast at Tiffany's or My Fair Lady among others.

She also was one of the women's best dressed list and the third greatest female screen legend in american cinema.

She died in 1993 due to a cancer.
