Carrie Underwood is Dolly Parton's number one fan.
The 33-year-old singer found a way to honor her idol during her concert in Los Angeles on Wednesday night, by singing her own version of one of 70-year-old Parton's most enduring hits, 1973's "I Will Always Love You."
"There were a lot of artists -- a lot of women, especially -- that, what can I say, I just fell in love with [growing up], but there was one in particular ... I don't know, there's just something about her," Underwood shared with her audience before the performance. "Her name is Dolly Parton."

"Over the years, I've come to realize that she just has that thing that all of us women in country want to have," she continued. "She has that career, she has just that personality. She does everything so well. She is an incredible storyteller, and songwriter and performer and vocalist. Everybody in the world knows Dolly Parton."
Underwood has covered the song before, including during opening night of her Storyteller tour in January. The song is obviously meaningful to the former American Idol champ, who sang the tune with Parton herself for her holiday special in 2009.

ET spoke to Parton in May, when the talked about her goddaughter, Miley Cyrus, and the Voice coach's reconciliation with Liam Hemsworth.
"I was really happy when I heard they'd gotten back together, 'cause I know that seemed to be a big heartache for both of them when that happened," she told ET exclusively. "That's good that they're back together."
