Don't worry, it wasn't anything too serious or anything! Taylor actually chipped a tooth!
In a recent interview with Rolling Stone, Taylor revealed details about her on-stage injury that night.
"Tonight I was particularly hung up on not chipping another tooth like last show in Pittsburgh, definitely. It had a tip on [the tooth] and it doesn't anymore," she said to the magazine.
"I try to be really quick with the microphone, so I'm not standing there just waiting to sing with my mic right next to my face, so I really quickly pulled my mic up to sing and basically uppercut punched myself in the tooth," Tay revealed about the whole incident.
"And then part of it fell onto the stage and I was like, 'Oh, I wonder how bad that was. I wonder which tooth that is and I wonder how bad that is,' and I was just trying not to chip another one tonight. I'm not doing anything about it. It's just gonna be a little bit jagged, I guess."
Tay's cosmetic injury occurred during her song "I Knew You Were Trouble."
One thing is for sure...at least we know Taylor's not a drama queen! A chipped tooth, especially when you're famous, can be something serious. You can't walk around with a messed up grill!
