Pink put on her mom hat over the weekend when she stopped singing "Who Knew" during a concert in Philadelphia to check on an upset little girl. "Is everything OK right here? Is this little girl all right? What's going on? Why is she crying? Why is she upset?" Pink asked. Someone in the crowd indicated that an altercation of some sort had caused the girl to get upset. "Because there was a fight? You all are fighting around a little girl? C'mon...all right, all right, I know, everyone's about to fight. I know, I'm from here." Pink offered the girl a treat to help her feel better. "Honey, do you want this frog and this Rice Krispie treat?" The girl was picked up and passed onto the stage where she accepted the gift.
