TLC's T-Boz suffers allergic reaction due to 'cigarette and recreational' smoke at show

Two TLC shows were delayed this weekend to allow T-Boz time to recover following an unexpected allergic reaction from smoke at one of their recent shows.

The Grammy-winning group, comprised of Tionne "T-Boz" Watkins and Rozonda "Chilli" Thomas, announced over the weekend that they had to move their show Saturday evening in Houston to Monday night.

"TLC has rescheduled the Saturday, October 2nd show at the Smart Financial Center in Houston, TX to Monday, October 4th," the announcement said. "Due to extreme cigarette and recreational smoke being present backstage at a previous show, T-Boz suffered an allergic reaction."

The statement continued, "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."

It was then announced that the group also had to move their Sunday concert in Irving, Texas, to Tuesday, Oct. 5.

"We are so excited to see all our TLC fans there!" the group tweeted.

The "Creep" singers' "CrazySexyCool" tour kicked off Sept. 3 in Alabama. The tour is a celebration of the ladies' now-iconic 1994 album "CrazySexyCool" and will pay homage to the 1990s by featuring themes and fashion from the decade.

To date, "CrazySexyCool" has sold more than 14 million copies since its November 1994 release -- making it the best-selling album by an American all-female group.

The album featured the hits "Red Light Special," "Creep," "Diggin' on You" and the group's No. 1 classic, "Waterfalls."
