Janelle Monáe performs ‘What Is Love’ on ‘American Idol’...

Brazilian carnivals are always fun, and Janelle Monáe brought that very atmosphere to 'American Idol' last night. As expected, Janelle delivered a lively, high-octane performance, and even her back-up dancers looked the part in their Brazilian carnival costumes!

Her funky new single 'What Is Love' is lifted off the soundtrack to the animated film 'Rio 2.'
