• This sassy, bluesy number features irreverent lyrics that capture Lambert's freewheeling personality.
  
  Mirror mirror on the saddle
  Hear my rhinestones rattle
  Actin' up
  Billy Bob Texas
  Picking out new exes
  Actin' up
  
  Lambert lives her life under her own terms and refuses to behave conventionally. She's had a successful career by doing things her own way.
  
  With my microphone money bought my own milk and honey
  Got my own kind of country, kinda funky
  Turn it up
• Lambert recorded "Actin Up" for Palomino; the album title comes from this song's chorus.
  
  I wanna see the desert
  From a painted Palomino
  Señorita need to have a little fun
  Mm, I'm actin' up
  
  A palomino is a horse with a gold coat and white mane and tail. Because of their distinct coloring, palominos are sought after as parade horses. Neil Young sang of saddling up the palomino on his 1977 country-flavored track of that title.
• Lambert wrote "Actin Up" with frequent collaborators Luke Dick and Jon Randall. Dick co-wrote nine of the 15 songs on Palomino. In 2021, Lambert dropped The Marfa Tapes, an acoustic project she wrote and recorded together with her fellow Texans, Randall and Jack Ingram.
• Lambert debuted "Actin Up" during her set at the Country 2 Country Festival in London on March 10, 2022.
• This is the opening track of Miranda Lambert's Palomino album. "'Actin' Up' felt right for the first song," Lambert told Audacy. "It sort of eases you into this journey. I thought, 'Let's get people in from like the first note, the first line of the song, especially the first line of a record, that's important. You can lose people quick!'"
