The singer revealed on Wednesday that she planned to keep her Houston concert date on Saturday at the city's Toyota Center.
"I'm here to tell you that we are doing the show in Houston. But we're gonna roll in early because we want to visit some of the shelters," she said in a video message on Twitter. "We also want to do something special for the victims."
Jackson is dedicating her concert to those affected by the hurricane and is donating proceeds from the show to local flood relief charities.
