The "Everywhere" singer went on to thank her husband, Black Keys drummer Patrick Carney, as well as her sister, for their support during the difficult time.
“But alas, between the crying and binge eating of Christmas cookies, I decided to put on lipstick and a dress. We drank champagne alllll day. Made an incredible meal and sang Christmas songs snuggled up by a roaring fire,” Branch wrote. “Five more days until 2021. I’m limping to the finish line.”
Her emotional post included a slideshow of family snapshots, including one of her cozying up to Carney, and others of her toddler son and teenage daughter.
"These people, my precious family, my husband, sister and kids have been the MVP’s," she continued. "I couldn’t imagine spending a year isolated with anyone else. Happy Christmas, everyone."
Branch and Carney started dating in 2015, and fell in love while working on her 2017 album, Hopeless Romantic, which he produced. The couple got married last year in New Orleans. The celebrity couple share a 2-year-old son, Rhys James.
Branch is also the mother to her 15-year-old daughter, Owen, whom she shares with ex-husband Teddy Landau. They divorced in 2015.
