Miranda's mom, Therese, took to Instagram to share gorgeous pics of the outdoor ceremony, explaining that while same-sex marriage isn't legal in Australia, "in the eyes of Matty and Jimmy's family and friends" the two have started a "beautiful life together."

"Even though Australia with its archaic beliefs does not yet recognize same sex marriage, in our eyes, in the eyes of Matty and Jimmy's family and friends and by the law of the universe that overrides all, Matty and Jimmy are married and have started a new and beautiful life together," she wrote. "We don't need an Australian Government or a law to tell us what love is or isn't."

Matty and his restauranteur beau exchanged vows "in front of 284 of their much loved and treasured family and friends," including Miranda's fiance, Snapchat CEO Evan Spiegel.
