Pretty sure Taylor Swift brought all of Santa Clara, California to tears Saturday night when she performed 'The Best Day' as a tribute to her mother and Camila Cabello's mom for Mother's Day. Currently on her Reputation Stadium Tour, Swift wanted to honor "anybody in your life who has mothered you..." and the song to her acoustic set. Each night she's been switching songs during her set so 'The Best Day' was the perfect song just a day before Mother's Day. Check out video below for her kind words and performance. Taylor Swift will be Chicago June 1st and 2nd.
