In his new role in the remake of Hairspray, opening today, John Travolta proves that he's still the king of Hollywood musicals, and a true Aquarian original. As 300-pound housewife Edna Turnblad, he may look like a cabbage-patch doll, but he was determined to embody a real woman, and even mastered dancing in a fat suit and heels. In his feminine form, Travolta says he was responsive to flirty, groping overtures from men on the set. "I offered myself up quite easily. And I thought, 'well, gee, would I have been a slut or what would I have been if I were a woman?' I scared myself a little bit there." Exploring this polarity, as a straight man, seems a likely path for someone with Jupiter in Gemini.

Travolta and wife of 16 years Kelly Preston are Scientologists, which in part has to do with harnessing the power of the mind. Both air signs, this Aquarius-Libra couple has elemental harmony down the line, with a few squares to spice things up. This summer, they're reportedly trying for a third child, and even deciding the sex. Says Travolta, "It has to do with positions and results and all sorts of intricate things."
