Witney Carson married her high school sweetheart, Carson McAllister, and the pair have been making fans swoon ever since. The Dancing With the Stars pro announced in October 2015 that her beau popped the question. "My love of four years @carson.mcallister proposed last night & I feel like the luckiest, happiest woman in the world.💍💕😍❤️," she gushed via Instagram. "It was perfect, he's perfect #engaged." It wasn't long before the twosome walked down the aisle. Carson and McAllister exchanged vows on New Year's Day in 2016.
