Demi Moore and Bruce Willis: The stars met at a movie premiere and married in 1987. Both enjoyed enormous career success in the 1990s, with films such as "Die Hard" and "Ghost." They have three daughters, and Moore famously posed nude for the cover of Vanity Fair while pregnant with their second child. The couple separated in 1998 but did not file for divorce until 2000. The exes remained close after their marriage ended, even vacationing together with their new significant others.
