The 47-year-old is famed for her youthful looks, which she puts down to her happy relationship with husband Ashton Kutcher. She has hinted she is ready to come up with a range of beauty products, explaining moisturisers are cleansers are something she is passionate about.
"I most definitely have and actually have a real passion for it that started going back to my name," she explained. "My mother named me Demi - which she found, as all things, as part of the name of a make-up."
Demi is famed for her unconventional beauty regimes. She has previously admitted using leeches to stay looking young, and also washes her hair with horse shampoo to keep it looking shiny.
The star works hard to stay in shape, but doesn`t obsess about her appearance. Her body changed during each of her three pregnancies, and she is proud of the last impression her kids left on her figure.
"My youngest, when she was quite small and we were on the beach, referred to the marks on my belly as my trademarks," Demi, who has three daughters with ex-husband Bruce Willis, told Hello! magazine. "There`s certain things I go, `Ugh, I`d really prefer not to have those. I don`t really like them to be seen, but at the same time, I`ve earned them.` "
