▲"My take on this is, first of all, why would Britney know my name? She's Britney, b****," he said on his show. "Britney is such an icon, I just feel like I'm not worthy of her knowing my name."

▲The two had shared a stage multiple times and filmed a music video for their song 'Slumber Party,' but that didn't stop Spears from mispronouncing her name at a 2016 show.

▲Spears's hilarious gaffe spurred fans on Twitter to urge Tinashe to change her name.

▲Spears got a little too comfortable at her show in London's O2 Arena on August 24, 2018, where she slipped into a version of an English accent that was uncomfortable for everyone else.

▲The fake English accent went viral, and fans seemed confused at whether they should cheer her on when she asked, “Are you guys ready? Do you think you can do this?"

▲Spears famously whipped out her English accent in confrontations with paparazzi in Los Angeles in late 2007 and early 2008.

▲The accent became deeply associated with her personal turmoil, which preceded a mental health crisis and hospitalization. So understandably its return is a bit unnerving.

▲In Taiwan a few years later, Spears once again forgot where she was, but this time she had a different approach, though it's hard to decide which was better.

▲When she performed at Brighton Pride in August 2018, her first UK performance in a couple years, she turned to a dancer and unabashedly asked, “Where are we?” before turning around and bellowing, “What's up, Brighton Pride?”

▲At her show in Blackpool, England, she asked the crowd, “How you feeling, Birmingham?” To be fair, she corrected herself, and fans tried not to point out the Blackpool Tower next to her.

▲She was lowered under the stage to change and didn't realize her mic was on when she said, “My p**** was hanging out!” consequently making the entire arena erupt in giggles.

▲Except Spears was their high-speed race car that never once slowed down. They traded in and out as the dancing continued, slowly zipping up the bodysuit.

▲At Rock In Rio in 2001, Spears's mic was on while she was backstage, and the whole audience heard her go on a profanity-laden rant.

▲Sometimes it is too painfully obvious, like at her 2017 show in Tokyo when her mic got severely tangled in her hair and 'I'm a Slave 4 U' kept playing unaffected.

▲If she lip-syncs so much, why is her mic always on to air her worst moments? Or does she forget her mic is always on because she's always lip-syncing?

▲In the epic opening for 'Toxic,' Spears is at the top of a huge tree from which she's supposed to fly over the crowd on a harness, only it totally and completely failed.

▲No firemen were necessary, only one panicked crew member who detached her harness. She just anticlimactically walked down the tree's stairs as the song played on.

▲Amidst the bondage, it appeared her tongue also became tied, and when it was time to acknowledge her guest, she blanked on his name. "I think you all know who this is," she skirted. "Give it up for him!"

▲Her mic was on and everyone heard her yell, "Willie! Willie, where are we?"

▲

During her Vegas residency in 2015, Spears nearly put herself out as she twisted her ankle while dancing and fell to the floor. Her painful grimace will not soon be forgotten.

▲Spears has the hardest working dancers on the Vegas strip, and it was never more evident than during her October 2015 show at Planet Hollywood when her sheer bodysuit was unzipped dangerously low in the back.

▲In other cases, her headset came loose or she would call out to the crowd and the sudden shock of hearing her real voice would pull the veil from over your ears.

▲While performing in the UK in 2009, Spears confidently asked the crowd, "What's up, London?" Which would've been fine if she wasn't actually in Manchester...

▲At a Tampa show in 2009, Spears had a major wardrobe malfunction—one of many—where her leotard ripped and her private parts were exposed.

▲In August 2017, during her Las Vegas residency, the pop star surprised her fans by actually performing a live cover of Bonnie Raitt's 'Something to Talk About'—and it wasn't a flub!

▲

"I'm a Southern girl, I'm from Louisiana. I'm from the South, and I like to keep it real, so I just want to make sure I keep giving you motherf******* something to talk about."

▲

In what was thought to be her first live performance of an entire song since at least 2009, she ditched the squeaky pop voice and delivered an uncharacteristically deep and powerful vocal timbre. In that same show, she delivered a monologue about the media and tabloids, something she acknowledged she's rarely done.

▲

"Don't tell me they're just letting the audience f***** stand out there like that," she said, before saying, “This is retarded,” and later, “I thought they were going to f****** vamp!"

Britney Spears has been in the unforgiving glare of the spotlight for years. The world watched her soar into stardom and tumble all the way back down, only for her to claw her way out of the mud and continue doing hundreds of shows a year and having millions of followers on her Instagram account. So, with that in mind, check out this gallery of her most cringeworthy onstage slips, trips, flubs, and memory lapses.

On July 24, 2018, at New York's Radio City Music Hall, she performed 'Freakshow' and invited the 'Watch What Happens Live!' host to be the bondage “victim” of her S&M routine.
