Singer Alicia Keys may be pregnant, but that’s not about to slow her down just yet. Last night at the 2010 BET Awards, Keys took the stage to perform her singles “No One,” “Try Sleeping With a Broken Heart,” and “Unthinkable (I’m Ready).”

But what really shocked viewers was when Alicia jumped on top of a piano during her tribute to music legend Prince, who was honored with a Lifetime Achievement award. Keys also was named “Best Female R&B Artist” and won best collaboration with Jay-Z for “Empire State of Mind”.
