• Brett Young wrote this song about the two "ladies" in his life: baby daughter Presley and wife Taylor Mills Young.
  
  You'll always be my baby
  But look at her
  Baby girl
  And you'll learn how to be a lady
  
  Young sings of his love for little Presley, and his admiration for Taylor, who will be his daughter's role model as she grows up.
• The song begins with Young recalling the first time he heard his baby girl's heartbeat when Taylor was eight weeks pregnant. The singer told Taste of Country Nights that he had written this song for his daughter before she was born on October 21, 2019.
  
  "Unfortunately, the first one I wrote I like so much that I haven't written anymore because I can't have an album full," he added.
• Young debuted the tune during his February 1, 2020 show at New York City's Hammerstein Ballroom. He continued playing "Lady" as the first song of his encore on his 2020 Chapters Tour.
• Brett Young knew he and his wife were going to have a daughter from early in her pregnancy. The singer calls Taylor "lady," and once they found out they were having a girl, they started referring to her as "little lady." With this in mind, Young put the title "Lady" in his phone as a possible song concept.
  
  Young brought his "Lady" song idea up during a session with Jon Nite and Ross Copperman a couple of months before Presley was born. Nite had previously co-written a song for Lee Brice titled "Boy." He recalled to The Boot that the songwriter had told him "he didn't want to do exactly that but for a girl; if we were gonna write it, let's do something a little different."
  
  Nite suggested rather than writing a song about Young's baby girl, they pen a message to his daughter about her mom. The message they came up with was telling the singer's little girl, "If you wanna really know how to be a lady, watch your mom."
• The song starts off with a sample of Presley's heartbeat, which Young recorded on a phone before she was born. It accompanies the opening line: "I remember when I first heard your heart beat." "She was a little musician before she knew it," the singer told People.
  
  Here are more songs that incorporate a heartbeat.
• Frequent Brett Young collaborator Seth Kupersmith ("Mercy," "Catch") directed the music video, which shows the singer hanging out with his family with plenty of sweet shots of baby Presley's smile. Kupersmith shot the scenes using only one camera and a drone while social distancing during the COVID-19 pandemic.
• When Brett Young co-presented Audacy's Superstar Power Hour, he told co-host Katie Neal it was way more emotional penning this personal song than recording it. "During the writing it was really emotional. I think a big part of that was because of the twist that we put on it where it brings Taylor in. It seems like a song about my daughter, but it's really not," he said. "It's a song about my wife that I've written to my daughter."
