In "The Rise of Clovis," after Clovis repeatedly asks about the relationship between Padmé and Anakin, Padmé asserts that "there is nothing romantic between he and I." The pronouns "he" and "I" are in the wrong grammatical case here; they should be "him" and "me." Presumably, as a senator, Padmé has a quality education and wouldn't normally make such a mistake, but her misuse of these pronouns indicates that she's flustered because of Clovis's suspicion - or perhaps even discernment - of the romantic relationship that does indeed exist between the two. It's also significant that Padmé separates herself from Anakin here; she says, "he and I" and not "us."
