Marlene Dietrich!
(from Wiki):
Dietrich was known to have a strong set of political convictions and a mind to speak them. She was a staunch anti-Nazi who despised Germany's anti-semitic policies of the time. Her singing helped here too, as she recorded a number of anti-Nazi records in German.
Dietrich became an American citizen in 1937 and entertained American troops during the Second World War. She is also famous for having recorded Lili Marleen during World War II, a curious example of a song transcending the hatreds of war.
Dietrich was a model which later stars would follow. Her public image and some of her movies included strong sexual undertones, including bisexuality. Accordingly, it is no surprise that she had affairs with women (Mercedes de Acosta was among her lesbian lovers) as well as men.
Unlike her professional celebrity, which was carefully crafted and maintained, Dietrich's personal life was kept out of public view. She married once, to film technician Rudolf Sieber. Her only child, Maria, was born in 1925. When Maria gave birth to a son in 1948, Dietrich was dubbed "the world's most glamorous grandmother."
