The gorgeous Liv Tyler has recently revealed that she has worn the C.O. Bigelow’s Musk Perfume Oil ($15) for many years. Her insider trick? She recently shared all of her beauty secrets in an interview with Into The Gloss and revealed that she puts little drops on her fingers and puts some under her arms and in her belly button – if you put it where you heat up, the smell will stay with you all day long. “And I’m telling you, every day, five people will ask me what I’m wearing,” Liv told the beauty site.
