Extreme cigarette and recreational smoke kept TLC’s T-Boz from performing for her “CrazySexyCool” concerts in Texas over the weekend.

The singer, who also suffers from sickle cell anemia, suffered an allergic reaction and the tour had to postpone two shows.

TLC’s Houston show, scheduled for Saturday, October 2nd, was moved to Monday, October 4th, and the Irving, Texas concert scheduled for Sunday, October 3rd was rescheduled for October 5th.

“Due to extreme cigarette and recreational smoke being present backstage at a previous show, T-Boz suffered an allergic reaction. The group has always enforced a strict no smoking policy at their shows in an effort to prevent any health-related issues for the group and/or crew,” a statement from the show organizers said. TLC has been touring with Bone Thugs & Harmony since September.
