Last night 11/13, Taylor Swift made a surprise visit to The Tonight Show With Jimmy Fallon to perform her song "New Year's Day."
This performance came immediately after Jimmy gave a heartfelt tribute to his mother, who passed away last week.
He told a story about how his mom would squeeze his hand 3 times to say "I love you."
In this song, Taylor sings the lyric "You squeeze my hand three times in the back of the taxi."
Jimmy was very emotional while talking about his mother and hugged Taylor when the performance was over.
