He was born to an American father of French-Italian heritage and a Scottish mother.
He was born to an American international banker father and a Scottish mother. Molko's family moved frequently during his childhood, growing up in Dundee, Liberia, Lebanon, and Belgian Luxembourg, where they eventually settled for quite a long time in the village of Longeau, just near to the border with Luxembourg, where the young Brian spent a lot of his childhood. This also explained his ability to speak perfect French. Brian Molko has referred to a period spent in his mother's home town of Dundee, Scotland, as "where I grew up".
While Molko was brought up in a strict household that disapproved of artistic expression (his father wanted him to become a banker), he rebelled by assuming an androgynous image, wearing nail polish, lipstick, and eyeliner, and listening to punk music. In his late teens, he came out as bisexual.
