Last month, the "Diamonds" singer was forced to cancel two dates after contracting laryngitis. She issued a heartfelt apology to her fans on Twitter, saying, "This is the hardest thing for me to deal with! I feel like we've been waiting on this day forever, and I'm hurt that I let you down. I hate disappointing people that never ever let me down!! I'm so embarrassed about this! Thank you for your prayers and well wishes!"
