The twice-engaged couple got married at A Little White Wedding Chapel in Las Vegas, Lopez confirmed via her On the JLo fan newsletter.
Lopez wore two different dresses: a sleeveless floral jacquard gown, which she said hailed from an "old movie," and a long sleeve off-the-shoulder lace dress with a matching veil. It's unclear when during her wedding she wore each dress.
Social media has turned into a full-blown frenzy as eagle-eyed fans and fashion blogs try to uncover what old movie she's referencing.
The singer has played a bride in nine films and has worn many wedding dresses in scenes from shopping for gowns to walking down the aisle.
