Demi Lovato has called off another show on her UK tour. The singer was scheduled to perform at the O2 Arena in London on June 10. However, she pulled out at the last minute, logging on to Twitter to tell her fans the bad news. “I write this through tears of frustration and sadness that I have to postpone my concert in London at the O2 tonight.” She said she was “very, very sick” and that she had “swollen vocal chords that were examined by a [doctor].” Lovato clarified that “if I go on tonight and injure my vocal chords… I could potentially have to cancel the rest of my tour.”
