Miley Cyrus vs. Liam Hemsworth! Which Celebrity Is Worth More in These 18 Hollywood Power Couples? (PHOTOS)

Who's worth more? Mariah

Mimi went for an older man with her first marriage to Tommy Mottola, so it’s almost fitting that her second stab at matrimony would be with a younger beau. Nick may be young, but he’s accomplished a lot at the age of 31. The America’s Got Talent host makes $70,000 per episode, and he’s fostered a busy acting career on both TV and film. He also runs his own label called N’Credible Entertainment.

But sadly, that’s nothing compared to his superstar wife. A bona fide diva (in the best way possible), Mariah has sold more than 200 million albums worldwide, making her one of the best-selling musical artists ever. Her acting never quite took off, but she’s also made money through partnerships with Pepsi and Motorola, as well as endorsements for Elizabeth Arden and Jenny Craig. She even jumped on the fragrance bandwagon with her own scent called M.

All of this brings the singer’s net worth to $500 million, while Nick’s net worth is estimated at just $25 million.
