Rianna Miller was the daughter of Kathy Miner. In 1999, Billy Abbott, Brittany Hodges, Mackenzie Browning, Raul Guittierez, JT Hellstrom and Rianna attended Walnut Grove Academy and were all friends. Rianna was dating "bad boy" J.T. exclusively, but he had a roving eye and treated her poorly. Her best friend, Brittany, had dated J.T. just prior and all three were close friends. Snobby rich girl Brittany snagged the Jabot Cosmetics heir, Billy, as her boyfriend. Straight-A students Raul and Mackenzie, granddaughter of Katherine Chancellor, were very close. Raul was falling in love, but Mac just wanted to be friends. Billy, Brittany, Raul and Rianna were chosen as the Glow by Jabot Kids, a summer promotion for the new Jabot teen line.
