But Andrea didn't let anything dampen her excited mood and resolve as she spoke proudly about her daughter's monumental achievements in music.
"I've watched this milestone artist from the time she was a tangled hair little girl growing up on our farm, full of imagination and creativity," an emotional Andrea said to the massive audience at the AT&T Stadium in Arlington, Texas. "And ever since then, her favorite thing in the world to do has been to write a song, tell a story, play a guitar, or a piano. And I've seen those things carry her through every emotion, every experience in her life. Good or bad."
Andrea also acknowledged the role she and Taylor's father, Scott, have had in their daughter’s music.
"Every once in a while, her dad or I find ourselves to be the subject of those songs. Sometimes we're merely the inspiration," Andrea said, smiling. "Like the time she was 17-years-old and her dad and I strongly disapproved of a young man, and rightfully so. But she was mad, she was real mad, and she went to her room and she closed the door. She came out about an hour later with a song called 'Love Story.'"
Mama Swift also showed some appreciation for how well the music industry has treated her baby girl.
"I'd like to thank the ACMs for honoring her in this way. But I'd also like to thank the entire music community for taking such good care of her," Andrea said. "And [to] the fans, I know you love her as I love her, And for that I thank you eternally."
"I am a very proud mom," Andrea added with tears in her eyes before introducing Taylor, who came out and embraced her mom a deeply emotional hug.
In her acceptance speech, Taylor also took the time to thank her fans in the country music community who stuck by her when she transitioned from country to pop with her album 1989.
"You truly see who a person is when you give them news that they weren't expecting," Taylor told the more than 70,000 people in the audience. "And so, to the country community, when I told you that I'd made a pop album and that I wanted to go explore other genres, you showed me who you are with the grace that you accepted that with."
