Moore, 42, known for her age-defying good looks, will appear in magazine and billboard advertising for the Italian fashion house, hellomagazine.com reported Wednesday.
Moore, star of "Charlie's Angels," "Ghost" and "GI Jane," was seen having dinner with Donatella Versace and photographer Mario Testino in London last week, the report said.
A spokesman for Moore denied talk that she is pregnant by 27-year-old boyfriend Ashton Kutcher.
"Having another child is something Demi would like to do, but she cannot at this time say she is pregnant," the spokesman said.
