Julius Caesar maybe - he was aged and she 22 and glamorous rather than beautiful by all reports. Antony, though - that sounded a lot more like love on both sides. She risked a good deal to pull him, wounded, up the battlements on ropes, and he was, on his part, reportedly agitated until he was assured of her safety and died shortly thereafter.
She was the last Egyptian Pharoah, the scion of a high Greek house, and a thoroughly formidable woman by any account. I do not know if hagiography is in order here, but she certainly wasn't a stupid Hollywood bimbo.
