The Swift-penned tune was up for Best Country Song at Sunday's ceremony.
Ahead of the 60th Annual GRAMMY Awards, Swift offered a sweet gesture to her LBT pals, sending a gorgeous arrangement of blooms in celebration of their Best Country Song nomination. The band's heartfelt hit, "Better Man," featured on their album, The Breaker, was penned by Swift.
"It was just really sweet of her to send [the song] in an email and say, 'Hey, I know you're making a record. Listen to this song, I love this song and I've had it in my back pocket for a while,'" Karen Fairchild told ET's Cameron Mathison on the red carpet. "She sent us flowers this morning, so sweet, just honoring the moment and saying, 'Can you believe it? We're at the GRAMMYs with 'Better Man,'" so it's a really special night for us."
"We have loved Taylor and been friends with her since she was a wee pup," Little Big Town's Kimberly Schlapman told ET on Friday night at the MusiCares gala. "We have always adored her. She's an incredible songwriter. She sent us this song and we fell in love with it instantly, and cut it and she loved what we did. It has been a great gift to us."
LBT is set to hit the stage during Sunday's telecast, where they say they'll pay homage to New York City.
While Swift's latest album, Reputation, wasn't released in time to qualify for the 2018 ceremony, the 28-year-old still scored two nominations. She was up for Best Country Song -- for writing "Better Man" -- and Best Song Written for Visual Media -- for her Fifty Shades Darker song, "I Don't Wanna Live Forever." The latter was awarded to Lin-Manuel Miranda's "How Far I'll Go" from Moana.
The GRAMMY Awards air on CBS on Sunday, Jan. 28.
