Livilla

Livilla (i.e., Claudia Livia Julia , 13 B.C. to 31 A.D.) was the daughter of Antonia and Drusus I, the brother of Tiberius. She was married to Drusus the son of Tiberius. Becoming the lover of Sejanus, together they poisoned her husband in 23 A.D. Sejanus asked permission of Tiberius to marry Livilla in 25 A.D., but Tiberius turned it down. He did grant the betrothal a few years later but Sejanus fell from his position and was executed before they were married due to Antonia letting Tiberius know that Sejanus planned to overthrow him. Livilla was given to the care of Antonia, who locked her daughter in her room until she starved to death.
