See All the Outrageous Moments From the 2017 Grammys!

When Adele cursed and restarted her tribute performance to George Michael.

"I can't do it again like last year," she said. "I can't mess this up for him. I'm sorry. I can't." She then restarted the performance and got a standing ovation.

When a pregnant Beyoncé worried the crap out of us with that chair stunt.

Beyoncé took a break from flashy dance moves in favor of a more laid back performance — literally. During the performance, she leaned back in a chair that was teetering on the edge of a table. It was impressive, but quite nerve-racking to watch.

When James Corden did "Carpool Karaoke" in the audience — and Blue Ivy joined in!

Of course, the five-year-old didn't know the words to "Sweet Caroline," but it was a sweet moment nonetheless!

And speaking of Blue Ivy, that moment when she was more interested in her purse than her mother's acceptance speech.

While Bey collected the award for Best Urban Contemporary Album, Blue was a tad distracted by her awesome, glittery purse. We don't blame her.

When Adele and Beyoncé had THAT moment together.

When Adele won Song of the Year, she thanked a tearful Beyoncé, who looked quite touched by the 28-year-old's speech.

"I wish you were my mommy!" Adele shouted to her.

When Lady Gaga and Metallica's performance was ruined by a mic failure.

Sure, Lady Gaga sounded great, but Metallica lead singer James Hetfield's mic didn't work for half of the performance. To compensate for the sound issues, Lady Gaga ran around the stage and jumped into the crowd.

When Rihanna reminded everyone how she gets through awards shows: by sneaking in a diamond flask.

She was caught on the live audience cam sipping out of it throughout the show — and now we want one too!

When Bruno Mars shaded the audience — in his own charming way, of course.

During his first performance, Bruno complimented the audience on looking great. "I still see some tags on those clothes, though," he joked.

When Nick Jonas was a complete gentleman to James Corden's mom.

The camera quickly captured this moment of Nick draping his jacket around James' mom.

When Twenty One Pilots accepted their award in their underwear.

The two told a story about watching the Grammys back before they were famous while wearing their underwear.

"Josh [Dun] turned to me — and we were no one at that time — and he said, 'You know, if we ever go to the Grammys, if we ever win a Grammy, we should receive it just like this,'" Tyler Joseph said.

When James Corden tried (and failed) to blend in with DNCE.

The host had the clothes and posture down, but couldn't quite nail the cool attitude.

When Katy Perry got political during her performance of "Chained to the Music."

She had the word "Persist" on her arm and the Constitution projected onto the stage.
