Nicki Minaj's career has been short but, so far, sweet. In the last five years, she's sported a number of unpredictable fashions, sounds and even personas, repping her own mixtapes, her first album "Pink Friday" (2010) and supporting artists from Madonna to Lil Wayne, David Guetta to Kanye West, Drizzy Drake to Mariah Carey.

The artist continues to tread lines between commercial pop and rap/hip-hop, and -- love her or hate her -- has opened up a wider lane for female MCs in this time. As the rapper/singer prepares the release of her sophomore set "Pink Friday: Roman Reloaded" for Cash Money on Tuesday (April 3), we look back at Barbz' biggest professional moments.
