It can't be possible that Demi Moore turns 54 today--mainly because the woman does. Not. Age. Seriously! Take it from her daughters Rumer, Scout, and Tallulah Willis, who at 28, 25, and 22-years-old, respectively, are starting to look like their mom more than ever these days.

After rising to stardom in the early '80s with her first-ever acting role on General Hospital, Moore was cast in the popular film, About Last Night (1986). Then, in 1990, Moore landed a role in Ghost, which was the highest grossing film that year. Going on to pursue parts in A Few Good Men (1992), Indecent Proposal (1993), and Disclosure (1994), Moore quickly rose to the top of the pack, cementing her spot among Hollywood's finest.

Moore married Bruce Willis on Nov. 21, 1987, and the duo welcomed their daughters in 1988, 1991, and 1994. Although Moore and Willis have split since then, the pair regularly come together for their children, and were most recently spotted supporting Rumer during her stint on Broadway's Chicago as Roxie Hart.
