Pop Stars' Most Embarrassing On-Stage Moments

When you're a performer doing hundreds of shows a year, mistakes are bound to happen. And the headlining acts on this list of pop stars' most embarrassing on-stage moments know that all too well. 

Just because you love a certain singer or musician, doesn't mean you can't still enjoy some of their embarrassing on-stage moments. You know, like when Miguel tried to leap over his fans, but ended up knocking one of them out. Or when Jennifer Lopez split her pants during one of her Vegas performances. And if you're really lucky, you'll catch the most epic of all embarrassing musician moments: the on-stage barf. (Both Justin Bieber and Lady Gaga have experienced this!)

Sure, you can be concerned when they fall (like Pink, Madonna, and Harry Styles have done), but these professional celebs always seem to get right back up! That's why their devotees love them - they continue performing even when the fans are yanking on them... literally. Beyonce's hair got caught in a fan during one of her performances, and she kept on singing!

Take a look at this list of pop stars' most embarrassing on-stage moments. Up-vote the most most cringe-worthy ones!

    Fergie infamously peed herself during a 2005 Black Eyed Peas performance. As Daily Mail reported, the singer finally opened up about it at the end of 2014 when she was interviewed on Hot 97. "It does not just happen all the time," she said. "We were late for stage, driving down the freeway, it's Friday traffic…get to the stage... I'm running on and we jump and do 'Let's Get It Started,' and I get crazy and I jump and I run across the stage and my adrenaline was going and gosh."

    No one will ever forget Ashlee Simpson's tragic SNL performance, where it was blatantly obvious that she was lip-syncing. 60 Minutes captured the whole thing - from the rehearsal where Ashlee was obviously concerned about her voice holding up for the performance - to the part where she danced her way off stage.

    Justin Bieber barfed on-stage during the Glendale, Arizona premiere of his Believe tour. According to The Hollywood Reporter, he later tweeted: "And... Milk was a bad choice! Lol."
  • When Katy Perry Got Caught Lip-Syncing

    It was so obvious that Katy Perry was lip-syncing during her performance at the NRJ Music Awards. As Gawker explained, there was a 15-second delay between what she was hearing in her ear piece and what the audience was hearing in the crowd. You can just see the embarrassment on Katy Perry's face when the host of the show asked the singer to start again... and when the singer had to actually sing.
