Shawn quickly got back up to continue his run from the main stage to B stage, but it didn't stop people from having a good LOL.
"How did the floor taste?" one fan asked, retweeting the video.
Shawn hilariously responded, "LOL wow. Tasted bad."
"São Paulo, I'm so so sorry to have to tell you this, but today I woke up feeling ill, and went to the doctor, to find out I have laryngitis and a sinus infection which has caused swelling of my vocal cords," he wrote in a note on Twitter. "It breaks my heart to do this but my doctors told me I can not perform tonight or it would risk long term damage to my voice. I love you all so much and apologize from the bottom of my heart as I wish I could be there on stage tonight. I promise I will make it up to you next time I'm back in South America. Te amo."
