Macklemore and Ryan Lewis had a pretty good night, taking home the Best New Artist trophy as well as sweeping Best Rap Song, Best Rap Performance and Best Rap Album. But the independent duo's most heartwarming Grammys moment came when they performed "Same Love," their pro-marriage equality hit, with Seattle singer Mary Lambert and a gospel choir. They were joined by 33 real-life couples, gay and straight, each of whom were united in love during an onstage wedding ceremony officiated by Queen Latifah. Also on hand: Madonna, who made a special cameo to sing a little of her own "Open Your Heart." That's one way to make sure everyone remembers your wedding.
