Celeb couples with big age gaps

Mariah Carey was married to Tommy Mottola (pictured), who's 21 years her senior, from 1993 to 1998. She then wed Nick Cannon, who's 10 years younger than her, in 2008. After they broke up, Mariah got engaged to the more age-appropriate Australian billionaire James Packer, who's only three years older than her. After they split, she quickly moved on with dancer Bryan Tanaka, who's 14 years her junior.
