Paulina's first husband was
Publius Memmius Regulus, a man of consular rank, who served as a suffect consul in 31 and later as a Roman governor.
Tacitus describes him as a man of 'dignity, who was a person of influence and good name', who died in 62. In 38, Paulina was with Regulus in the province he was governing when Caligula ordered her to leave her husband upon overhearing a remark about the beauty of her grandmother. She was forced to divorce Regulus and marry Caligula, becoming his third wife and Roman Empress that same year. Caligula divorced her after six months of marriage, ostensibly because she was infertile, and forbade her to sleep with or associate with another man. In 48, Paulina became a rival to Caligula's sister
Agrippina the Younger. Paulina was considered as a potential fourth wife for Caligula's paternal uncle, the Roman emperor
Claudius, following the execution of his third wife, the Roman empress Valeria
Messalina. In 49, Agrippina the Younger married Claudius. Sometime after, Agrippina the Younger had Paulina charged with
sorcery, accused of having entered into forbidden consultations with astrologers. Without a hearing, Paulina's property (including
her gardens) was confiscated and she was sent into exile. Tacitus reported that Paulina was forced to commit suicide under the watch of a colonel of the Guards and implied that this was done on the orders of Agrippina the Younger. A
sepulchre was not erected in her honor until the reign of the Roman emperor
Nero. ==Reputation==
