And on Friday, before her Houston concert at the Toyota Center, Jackson visited the evacuees at their shelter with her brother Randy Jackson and the Mayor of Houston, Sylvester Turner.
Janet Jackson is known for her composure and calm demeanor, but the new mom had a rare emotional moment during her latest concert in Houston, Texas. The lyrics to the emotional number - which is about domestic violence and infidelity - include: "What about all the s**t you've done to me?"
Jackson, 51, sang her hits like "Nasty", "Miss You Much" and "All For You", while interacting with fans in the crowd.
"Elements of the song have to do with me", she said to Rolling Stone. Jackson, who is in the midst of a divorce from estranged husband Wissam Al Mana, father of her newborn son, Eissa, struggled to get through the lyrics to the defiant tune.
Janet performed her song "What About" from the 1997 album "The Velvet Rope".
While taping into the Rhythm Nation-era, Janet sported several 90's inspired looks that flaunted her post-baby figure.
As previously reported, Jackson postponed her Unbreakable World Tour in May 2016 when she announced she was expecting.
She promised the flood-ravaged city of Houston "something special" on Wednesday.
Jackson is on the second part of her tour, which she renamed her "State of the World tour" after putting it on hold for her pregnancy.
She says she plans to visit some of the victims of the massive storm and let people know she cares about their plight.
