In 33, Julia married Gaius Rubellius Blandus, a man from an equestrian background. Despite that Blandus had been consul suffect in 18, the match was considered a disaster; Tacitus includes the event in a list of "the many sorrows which saddened Rome", which otherwise consisted of deaths of different influential people. Their children were Gaius Rubellius Plautus and possibly a daughter Rubellia Bassa who married a maternal uncle of the future Roman Emperor Nerva. Juvenal, in Satire VIII.39, suggests another son, also named Gaius Rubellius Blandus. An inscription suggests Julia may also have been the mother of Rubellius Drusus, a child who died before the age of three.
