There were a lot of brand new acts showing their stuff at the Billboard Music Awards this year!
But Jennifer Lopez decided it was time to show these kids how it's done!
Ch-ch-check out the video (above) to see Jenny from the Block rock the BMAs, with a little help from Pitbull!
We guess Pitbull is a firehouse dog because J-Lo is really working that pole!
Si! The Billboard Music Awards needed a little Latin love!
And who better to do it than Pitbull and Christina Aguilera!
But they also had a little trick up their sleeve, as they were joined on stage by Morten Harket of A-Ha to do a surprise performance of Take On Me! How awesome is that!!!
Ch-ch-check out the video (above) if you're ready to Feel This Moment along with them!

Did we mention how much we've LOVING Xtina's new look?
Christina Aguilera has been wowing us on the red carpet lately and, though she skipped the Billboard Music Awards' blue carpet, she KICKED ASS during her performance of Feel This Moment with Pitbull.
The 32-year-old cut a supremely STRIKING figure in Versace top with plunging neckline and gold fringe, a Herve Leger skirt and Christian Louboutin heels.
Simple yet sublime — this is how Xtina should ALWAYS dress!
And those luscious golden curls were the cherry on top!

Ay, papi chulo — Mr. 305 is muy caliente!
Pitbull and Jennifer Lopez blew us all away everyone but Mariah Carey away on the American Idol stage last night & now they've done it again!!!
Just the idea of these lovely latinos making music together is AH-Mazing enough already, but we had no idea it would turn out so damned seXXXy!!
Ch-ch-check out Live It Up for yourself (above)!
From her toned bikini body to rolling around On the Floor in sex-ay French lingerie, J.Lo looks so marvelous!!!
And, bouncing back and forth between haute couture runways in Paris & the sunny beaches of Miami, we finally understand why they call him Mr. Worldwide, LOLz!!
More importantly, the song is great!!!
We need to SHAKE our rump to this dance-tastic track right now!!!
We knew that Jennifer Lopez and Pitbull were bringing an inevitably SEXY spectacle to the American Idol finale, and the so-hot-it-hurts pair did NOT disappoint!
Prepare to SHAKE your asses and watch JLo and Pitbull's live performance of Live It Up from last night's Idol (above)!
Now wait… HOLD UP!
Is Mariah Carey the ONLY AI judge who doesn't stand up and clap for Jennifer at the end of her killer dance number?! UMMM YUP!
We guess the Beautiful butterfly queen really DID get pissed about those rumors claiming Idol execs wanted to replace her with Jenny Jen!
Oooof, awkkkwarrd!

Inneresting… we don’t quite know what to make of this.
Is Ke$ha being nice by going out of her way to bring her dance-tastic music to some of the less-populated towns, or is this pop singer’s career totally backsliding??
Ke$ha is already touring this summer with Pitbull, but she just announced her own headlining North America tour that will take place in August. However, the places she’ll be playing at include isolated areas and State Fairs!!!
For instance, one of the locations listed is Gilford, New Hampshire. In case you weren’t familiar with Gilford (as most people aren’t), Gilford is a small town with a population of barely 7,000 according to the last census.
And then, of course, she’ll be at the Illinois State Fair.
View her full list of tour dates to see if she’ll be hitting up the State Fair near YOU …AFTER THE JUMP!!!
We're getting a lot of images of glitter and cocktails with this one!
Jennifer Lopez has just released her newest single, Live It Up, off her upcoming TENTH studio album!
And with it, one thing is official — she and Pitbull TOTALLY get the meaning of SUMMER dance sounds!!!
Ch-ch-check it ouuttt (above)!!!
She and Pit recently worked on the music video for the pumped up jam when reports of gunshots caused an early evacuation. Luckily, nobody was hurt, leaving everyone to truly LIVE. IT. UP!
Produced by RedOne, we're feeling the future of this hit in clubs everywhere!!
