Brandi Cyrus and Matt Southcombe are celebrating the holidays with an engagement. "It's been the craziest, biggest year of my life and I get to close it out saying YES to forever with my dream man," Cyrus, 38, captioned an Instagram post on Friday, December 26. "I'm so thankful everyday that my flight got cancelled and I walked into this coffee shop one afternoon and found you. You're my very best friend and everything I've spent my whole life looking for. I love you forever!!!" The DJ shared photos of her engagement, which showed Southcombe down on one knee next to his motorcycle.
