No one could have expected a young Nickelodeon star to dominate the pop industry in the way Ariana Grande has. At only 25 years old and showing no signs of slowing down, Grande already has three number one albums to her name, and was just named Woman of the Year by Billboard in 2018. The sky’s the limit for Grande, as she’s well on her way to a compelling case for the top spot on this list.
