#usparenthood You thought your sister was mean to you.Rhianna takes it a whole diffrent level. The only reason rhianna gives her sister a hard time is because she killed her mother. When rhianna was a kid she went to her little sister brith, & rhianna already didn't know her father because she didn't have one.So once the docter came out of the room half way crying she gave her the baby and said she's dead they had to go to a ophage & rhianna felt like her life was ruened
