Mariah Carey is known as one of the top divas in the music business and this week may have won the R&B songstress the title for good. Mariah took to social media to share photos of herself working out. While that's not uncommon for celebrities to do, Mariah looked a tad over dressed rocking a skin tight bomber jacket and white 4-inch heels. However, that didn't stop her, she ran, lifted weights, and took on the stair climber alongside her trainer.
