LeAnn Rimes revealed that she has to reschedule more concerts amid her ongoing health issues. "After a follow-up visit with my doctor, she has strongly advised me to take an additional week of vocal rest while I heal from this sickness," the singer, 43, wrote via her Instagram Story on Tuesday, May 12. "This sadly means I can no longer perform this weekend in Washington and Wilmington." Rimes explained that the shows were not canceled but postponed. The Washington D.C. show is now scheduled for August 15, and Wilmington, Delaware will be on August 16.
