It’s not quite 30 tons of trash, but a sizable mess was made, yet again, at a Kenny Chesney concert.

Britney Spears spent Halloween night performing a concert at London's Wembley Arena with Joe Jonas, whom she recently signed on to the European leg of her Femme Fatale Tour. The downside of performing a concert on Halloween, of course, is missing out on all of the trick-or-treating fun. But luckily for Jonas, Spears made up for the candy shortage by performing a little striptease for him, complete with semi-awkward straddling! Here's an incredibly clear and up close video of it.

During a concert in Belo Horizonte, Brazil on Tuesday, Avril Lavigne was about to begin a cover of Coldplay's "Fix You" when a rogue superfan approached her after gaining access to the stage. Lavigne's security team acted quickly to remove the assailant, but not before she let out a fearful shriek, as you'll see in the video above. [via ONTD]

Lady Gaga kicked off Good Morning America's Summer Concert Series today before a record crowd in Central Park. The spectacle wasn't without its technical difficulties, though, as Gaga failed to appear on stage until near the end of her opening number due to a stubborn zip-line.

Today on The Internet's Funniest Home Videos, here is Lady Gaga slipping and falling while performing "Poker Face" at a recent gig in Atlanta. This is great because we get to see the fall over and over again from every angle.

Last night, Prince performed a concert at Madison Square Garden. During the show, he invited Kim Kardashian on stage to dance with him. But she just stood there awkwardly! So, he kicked her ass off the stage like a boss.

Tonight, Lambs across America were glued to the television watching Mariah Carey's holiday concert special, which included a duet of "O Come All Ye Faithful/Hallelujah Chorus" with her mother, Patricia. And in true diva style, Carey upstaged Mom. Watch inside.

Japan isn't exactly known for being normal, we know this. But did you ever think you'd see a concert—attended by thousands of screaming fans—that starred an anime-like hologram? Whether you did or not, here it is. Watch inside.

Beliebers, convene! Non-Beliebers, cringe! Hot off the press, here's the first official trailer for the upcoming Justin Bieber documentary/concert film, Never Say Never, presented—for some reason—in 3D. It's kind of like the trailer for Secretariat, no? Watch inside.

This is schadenfreude at its finest! Check out this video of Demi Moore "dancing" on stage with Snoop Dogg and husband Ashton Kutcher, during a recent Las Vegas concert. If Moore had a day job, she should stick to it.

Tonight brought us the season finale of Shaq Vs., a show in which Shaquille O'Neal issues challenges to celebrities. This time, it was O'Neal vs. tween sensation Justin Bieber. Video of their dance-off—and O'Neal rapping at Bieber's concert—inside.

And the award for coolest kid ever of the day goes to... Yuto Miyazawa, a 10-year-old Japanese guitar prodigy, who was invited on stage by Ozzy Osbourne at a recent Connecticut concert to perform "Crazy Train" with him. Watch inside.

Like me, you've probably always wondered what it'd look like for a sign language interpreter to perform lyrics like, "My hump, my hump, my hump, my hump, my lovely lady lumps," at a Black Eyed Peas concert. Here's your answer.

Performing in Hamburg last week, Rihanna turned around, dropped her microphone, and attempted a moonwalk—but ended up tiptoe-tottering backwards in pathetic slow motion instead.

Alanis Morrissette is gorgeous and genius, if a tad needy, and her ex Ryan Reynolds is a vapid lump of bad actor who never deserved her. Which is why what happened at her listening party the other night is so awesome. "'Every time I go through something difficult, I think, this is the mother load. I'm not going to get through this one,' Alanis Morissette said last night during an intimate performance in New York. 'And then six months later I'm like, what's his name again?' And with that, the journal-spewing Queen of '90s Rock quashed any rumors that she was heartbroken over her ex-fiancé Ryan Reynolds' recent engagement to Tom Waits admirer Scarlett Johansson."
