The ceiling at the Billboard Music Awards really couldn't hold Macklemore & Ryan Lewis!
The Seattle duo performed their smash hit Thrift Shop, and just like his PJ's from the music video, it was AWESOME!
Ch-ch-check out Macklemore as he brings the house down (above)!
Breezy in the hizzouse!!
The Billboard Music Awards may give Chris Brown the award for Top R&B Artist, but CB gave the BMAs some top R&B first!
Ch-ch-check out his performance of Fine China (above) to see what we're talking about!!!
Wowzers!!!
Regardless of whether or not you agree with his off-stage behavior, you can't deny his on-stage moves!

10101101001!
That's binary for "ZOMG, we can't believe that just happened!'
Carly Rae Jepsen just took home the cake — mmm, cake! — for Top Digital Artist at the 2013 Billboard Music Awards and she totes deserved it!!
Gurl used her online presence to beat out Flo Rida, fun., Maroon 5, and Taylor Swift!
Wow! Color us impressed, Carly!

This skater girl does NOT age!
And it's not just because she's standing next to her 38-year-old fiance Chad Kroeger.
Avril Lavigne posed on the blue carpet in a seksi leather Wakami strapless dress and cut-out boots at the Billboard Music Awards in Vegas on Sunday.
It wasn't her worst look, but it wasn't her best either.
We're kinda ready for the 28-year-old to get a bit more polished with her red carpet ensembles.
That ombre hairdo can hit the road, too!

Our heads are spinning! And so are Icona Pop!
The DJ duo took the stage at the Billboard Music Awards and let's just say we Love It!
Ch-ch-check out the video (above) to see girls werk it!
Hold on to your ten-gallon hats, because this is amazeballz!!
The Billboard Music Awards wouldn't be Done without a performance by The Band Perry!
Ch-ch-check out the video (above) to see the country trio perform Better Dig Two!
ZOMG they're just the best!

Hmm. We're not sure what's going on here.
Chloë Moretz can pretty much always be counted on to look ON POINT at any event, but at the Billboard Music Awards in Vegas this afternoon, she left us totally perplexed.
Her patchwork, belted Fendi mini dress looked like a sartorial Frankenstein — too many random pieces stuck together and it didn't work!
On the bright side, her soft, sleek blowout was beautiful!
Thoughts???
