Rumer Willis "never" tells anyone what fragrance she wears.
The 27-year-old actress has admitted she doesn't like revealing what perfume she uses because she doesn't want anyone to copy her, although she has revealed she sprays a mixture of "weird s**t".
Speaking about her signature scent, the 'Return to Sender' star said: "I never tell anybody. I don't want anyone else to have it. I mix stuff; it's like random, weird s**t. [I will mention] Kilian--they make beautiful stuff."
However, the brunette beauty is more open to sharing the cosmetic products she adorns on her face.
And the 'Dancing With the Stars' champion - who was crowned winner of the reality television show last year - won't wear too much make-up during the daytime, and prefers to keep her everyday look "very light", although she will apply a touch of rouge lipstick for the evening.
Speaking about her beauty essential, she said: "Bronzer and very light. I feel like you shouldn't have a lot of make-up on during the day. Most of the time, I'll do just a bit of eyeliner on the top. Super kind of retro has been my vibe. I've been wearing red lipstick more at night.
"Never blush. I don't like it at all, always bronzer. I have the Tom Fordone and I love it."
But the Kentucky-born star will never make-up to work out because it's "too much effort".
She explained to E! News: "Oh my god no. That's like so much effort, and then I feel like it would just end up sweating off my face anyway."
Meanwhile, Rumer - who is the daughter of actor Bruce Willis and Demi Moore - has teased water is the secret to achieving a "magic" complexion.
She said: "Honestly, drink water. You're supposed to drink half your body weight in ounces per day, which is crazy, and I don't think anyone drinks enough water. If you do that, your skin will be magic."
