On Monday (Dec. 23), the 24-year-old shared a piece of her childhood on the Internet, posting a video of her four-year-old self chatting on the phone on Christmas day.
"Christmas 1993, on a very important phone call with Britany. @britmaack," Swift wrote along with the video.
In the clip, Swift doesn't seem particularly pleased to be receiving a phone call from her friend, whom she asks in a demanding tone, "What? Britney, what? What is it?"
Meanwhile, Swift revealed she also gets into the holiday spirit by listening to some of her favorite Christmas tunes.
"[There are] so many! Colbie Caillat has a great Christmas album I’m obsessed with. I love the She & Him Christmas stuff. Bing Crosby, of course. 'All I Want for Christmas Is You' by Mariah Carey. Beach Boys have great Christmas music," she told Entertainment Weekly when asked what her go-to song was to start the Christmas season off each year. "Train has this song called 'Shake Up Christmas.' I have so many favorite Christmas songs right now."
