The album's third single, "Peter Pan", was released to country radio on March 21, 2016. "Peter Pan" reached number one on both the Country Airplay and Hot Country Songs charts in September, making Ballerini the first solo female country music artist to top both country music charts simultaneously. This achievement also made her the first solo female to send her first three singles to number one since Wynonna Judd accomplished the same feat in 1992. The album's fourth single, "Yeah Boy", was released to country radio on October 10, 2016.
Kelsea Nicole Ballerini (born September 12, 1993) is an American country pop singer and songwriter. She began songwriting as a child and signed with Black River Entertainment in 2014, releasing her debut studio album the following year, The First Time. Her second studio album, Unapologetically, followed in 2017. Ballerini's first two albums have accounted for seven charted songs on the Hot Country Songs and Country Airplay charts. She has four No. 1 singles on the latter, starting with her debut single "Love Me Like You Mean It", which made her the first female artist to send a debut single to the top of that chart since Carrie Underwood in 2006. It was followed by "Dibs" and "Peter Pan", whose peaks also made her the first female country artist to send her first three singles to the top of that chart since Wynonna Judd. Ballerini's fourth No. 1 single is "Legends". Her third and fourth studio albums, Kelseaand Ballerini were both released in 2020.
At 19, she signed a deal with Black River Entertainment. In late 2014, she released her debut single "Love Me Like You Mean It", which debuted on the Country Airplay chart in October 2014.

For the chart dated July 4, 2015, "Love Me Like You Mean It" , the album's first single, reached number one on the Billboard Country Airplay chart, making Ballerini the first solo female country music artist to score a number one hit with her debut single since Carrie Underwood did so with "Jesus, Take the Wheel" in 2006, and only the eleventh in history to achieve the feat. Ballerini also became only the fifth solo female country music artist to score back-to-back number one hits with her first two singles when "Dibs", the second single from the album, reached the top of the Country Airplay chart. She became the first to do it since Jamie O'Neal in 2001.

Ballerini has been influenced by both artists in the pop music and country music field. Originally influenced by pop music, Ballerini states "I grew up on top 40 pop. I didn't know what country music was, which is so funny because I grew up on a farm in East Tennessee." Ballerini lists Britney Spears, Christina Aguilera, and NSYNC among these early artists influencing her. Ballerini also cites Justin Bieber as an early pop musical inspiration. It was not until Ballerini heard "Stupid Boy" by Keith Urban that she decided to delve deeper into country music by listening to albums by Taylor Swift, Sugarland, and Dixie Chicks. She credited Swift's self-titled debut studio album for introducing her to country music. Ballerini also cites Shania Twain as her greatest influence. She has also performed songs originally recorded by Alison Krauss and sang "Ghost in This House" alongside Krauss at the CMT Artists of the Year Awards in 2018.
