Wiz Khalifa, Lil Wayne Win Billboard Awards

The 2012 Billboard Music Awards were held last night (May 20th) at the MGM Grand in Las Vegas. There weren't a whole lot of surprises in what turned out to be an entertaining but fairly stale show. Chris Brown took home the award for Top R&B Artist, with LMFAO landing Top Duo/Group and Hot 100 song awards.

Lil Wayne and Wiz Khalifa both took home awards at the big show, as well.

The late Whitney Houston was honored with a tribute by John Legend and Jordin Sparks, with Alicia Keys joining the legendary Stevie Wonder onstage when he was celebrated with a Lifetime Achievement Award.

Justin Bieber was named "Top Social Artist."

Pharrell Breaks Down "Glory"

Superproducer Pharrell Williams decided to share some facts about "Glory," Jay-Z's tribute song to his baby daughter Blue Ivy. Pharrell, who produced the track, says that the idea was premeditated and intended to also be a nod to Stevie Wonder's 1976 classic "Isn't She Lovely"--which was also a tribute to his newborn daughter.

"It was something we had planned before it happened, so we were basically waiting," he said. "That was like our nod and homage to when Stevie [Wonder] did it for his baby, Asia [on 'Isn't She Lovely']. And we weren't trying to make the same song at all, it was like we wanted to capture a moment in time to commemorate the birth of his baby. I did the same thing with [my baby] Rocket, I'm just more quiet and private about my life."

"But he and his beautiful wife, they live a different lifestyle and for him it was important for him to stop everything that he had going on and just sort of make statement to his baby and his wife," he said. "I was honored to be a filmmaker for that beat."
