Hannah is a single mom of Tom. Her Fiance cheated on her with 2 other women at the same time that produced kids. All the teens have the same father. Skyler's mom died so Hannah took her in, in her eyes, this is just as much her kid as her son, after all they are siblings. Later Lilly moved in, she started to hit big with her music, but really wanted to help her siblings, so she moved in with her siblings and their adoptive mom in order to get to know them and help out money wise. #looklilsimsie
