Lucullus married her on his return from the Third Mithridatic War around 66 BC, after divorcing his first wife Claudia. Servilia bore him a son whose name is uncertain. She was unfaithful to her husband with his enemy Gaius Memmius. Lucullus, after putting up with her conduct for some time out of regard to Cato the Younger at length divorced her. On the outbreak of the civil war in 49 BC, she accompanied Cato, with her child, to Sicily, and thence to the Roman province Asia. Cato left her behind in Rhodes, while he went to join Pompey.
