Eleanor Jackson is the female half and singer in La Roux, an English electro-pop band. She was born born on March 12, 1988.
The band's name, La Roux, refers to her hair. From wiki:
"To me, it means "red-haired one" – and it does, vaguely. It's just a male version of "red-haired one", which I think is even cooler, because I'm, well, androgynous anyway. So it kind of makes sense."
She has this very nice androgynous look and experiments with makeup, sometimes even seeming to go without.
