What language did Boudica speak?

Boudicca, whose real Iceni name is still not known, at least so far, certainly spoke a form of Goedilic-Gaelic common to Britain (probably resembling Welsh) at that time (60AD) and likely did understand Latin, as her husband Pragastus dealt with the Romans regularly. She probably also spoke regional tribal dialects but we do not know of her command of spoken Latin.
