Nicki Minaj is polishing some new trophies after Sunday's Billboard Music Awards.  The Young Money rapper walked away from the ceremony at Las Vegas' MGM Grand with three awards.  The "American Idol" judge beat out her all male competition to take home the trophy for Top Rap Artist.  
Minaj also came away with awards in the categories of Top Streaming Artist and Top Rap Album for Pink Friday: Roman Reloaded.  Macklemore & Ryan Lewis also had a big night.  Not only did the rapper-producer duo take the stage as performers, but their hit song "Thrift Shop" won the award for Top Rap Song.  Meanwhile, Rihanna took home four awards, including Top R&B Artist and Top R&B Album.  Other big winners Sunday night were Taylor Swift, One Direction and Justin Bieber.  

The awards ceremony also boasted a number of big name performances.  Miami-born rapper Pitbull not only teamed up with Christina Aguilera to perform their track "Feel This Moment," but he took the stage a second time to perform with Jennifer Lopez.  Nicki Minaj followed up her wins with a steamy performance of "High School" with Lil Wayne.  Miguel, Prince, Taylor Swift, Chris Brown and Justin Bieber were also among the artists who performed at the awards ceremony.
