Yep.
Hera decided that for this murder of Zeus's flings, she'd disguise herself and make Semele doubt that her lover was actually Zeus and convinced her to ask Zeus to show her his true form.
Shortly there after, Zeus promised Semele to do one thing she asked of him and, IIRC, swore on the River Styx either for unrelated reasons or in response to her sudden doubts about him. Semele promptly asked to see his true form and Zeus, to his credit, did try and talk her out of it. Unfortunately, she was adamant and Zeus, bound by his oath revealed his true form and vaporized her.
