Stock up on home power generators and start filling your bathtubs with water because Beyoncé will soon perform in a city or town near you. Riding high on the momentum of her Super Bowl blackout-worthy performance, Bey announced late last night a 2013 world tour titled "The Mrs. Carter Show World Tour." Details after the break.

Justin Timberlake got decked out in his finest when he took the stage last night for DIRECTV Super Saturday Night in New Orleans!

He performed his song “Suit & Tie” live for the first time and yeah, we'll say that he's been missed!

Justin also debuted a few new tracks! Clips after the jump!

Beyonce just sang the hell out of "The Star Spangled Banner" at her pre-Super Bowl press conference!

"Any questions?"

Nope. We're good, Bey 

Watch after the jump!

Are the rehearsals (or do they call them practices?) of the 49ers and the Ravens this exhilarating? No one will ever know. But we do know one thing: we are counting the seconds until Sunday's big Beyoncé concert more impatiently than ever after laying our eyes on the first rehearsal video for the performance!

President Obama's gay-heavy speech was certainly a show stopper, but Beyoncé and Kelly Clarkson may have stolen the show. Videos of their respective performances after the break!

Noah St. John, 15, won NPR's Snap Judgement Performance of the Year for his electrifying story about his two moms. Grab the Kleenex and follow the jump for the award winning performance!

The judges and contestants at NBC's The Voice (plus Carson Daly), brought their respective voices together for a truly stirring rendition of "Hallelujah" in tribute to the shooting victims in Newtown, Connecticut.

We've still got goosebumps. 

Check it out after the jump.

Lady Gaga was handpicked to join The Rolling Stones on stage at their 50th Anniversary Concert, but does Mother Monster have moves like Jagger?

Find out when Gaga teams up with the Stones for "Gimme Shelter" after the jump!

This is making the rounds of the interwebs today and it left us pretty speechless.

Check out Yoko Ono's stunning cover of Katy Perry's "Firework" after the jump.

Rihanna certainly delivers the hits but sometimes hits the mark in the delivery of her live performances.

Maybe it just took a decade for the international pop star to find her range?

Check out a medley of "Stay" (from Unapologetic) and "We Found Love" from the U.K. X-Factor after the jump and let us know what you think.

It's weird going from thinking Glee was cancelled years ago to realizing it's still kicking thanks to a socialite-heavy rendition of "Let's Have A Kiki" that's gone viral in less time than Kanye West did after he started dating Kim K. 

So, if you want a campy reminder of Glee's existence, follow the jump for a questionable mash up of Kiki and "Turkey Lurkey" starring Sarah Jessica Parker, Shangela, and other NYC creatures of the nightlife. 

We've all been bellowing Rihanna's "Diamonds" since it came out, but we have to admit, we've been curious about what the Sia-penned song would sound like straight from the pipes of its creator.

Sia delivered an acoustic rendition of the smash hit at the Norwegian-American Achievement Award Ceremony on Wednesday, and we have to say it's pretty gorgeous. 

We can definitely hear Sia's influence on Rihanna's vocal take. Check it out after the jump!
