Met Gala 'Heavenly Bodies' theme inspires spacey celeb looks

The theme of this year's annual Met Gala fundraiser, "Heavenly Bodies: Fashion and the Catholic Imagination," will, says the Met, "feature a dialogue between fashion and medieval art from the Met collection to examine fashion's ongoing engagement with the devotional practices and traditions of Catholicism."

Some celebrities, like Rihanna in her stunningly bejeweled pope hat and Chadwick Boseman in his cross-bedecked robe, adhered closely to the theme with Christian iconography. Others, like Lana Del Rey, went back to the Middle Ages with some variation of Renaissance or Game of Thrones chic. 

Still others walking the New York red carpet before the star-studded Monday night event brought a certain futuristic celestial glam to their own heavenly bodies. They donned ethereal shimmery fabrics and elaborate headwear that could be at home in a sci-fi franchise. Here are some of the more cosmic looks.
