Aguilera has been talking a lot lately about her new fragrances "By Day" and "By Night."When asked by StyleList who her beauty muses were, she replied:
"I thought of my favorite classic beauty icons when I started making the fragrances. I wanted to incorporate old Hollywood vintage glamour and that red lip into a sexy and sensual feeling. Marilyn Monroe is my favorite — I think she evoked sensuality in her look, walk and talk — and she just oozed natural confidence."
