Songfacts®:

• Harry Styles wrote this song about being away from his girlfriend. After a couple of days of separation, they are already missing each other and do a lot of late-night talking through video calling.
• The shiny R&B tune had Harry's fans late night talking as they wondered whether this song is about his relationship with the actress and director Olivia Wilde. The pair began dating after meeting during the filming of Wilde's Don't Worry Darling movie. One of the lyrics hints that Styles' love interest is in the movies:
  
  But I'd follow you to any place
  If it's Hollywood or Bishopsgate, I'm coming too
• "Late Night Talking" was the first song Styles wrote for Harry's House in the studio. One of his songwriting partners, Tom "Kid Harpoon" Hull, was there, but his collaborator, Tyler Johnson, hadn't yet arrived. "First day, we were setting up and it was just me and Tom," Styles told Apple Music. "We got there early and we wrote 'Late Night Talking.'"
• Kid Harpoon played all the instruments on the track: synthesizer, bass guitar, drum machine, drums, electric guitar and tambourine.
• Styles debuted the song during his Coachella 2022 set on April 15, 2022. He released it on May 20, 2022, as the second single from Harry's House.
• The Bradley and Pablo-directed video finds Styles performing the song in various beds with various guests across several locations. After waking up in his own bed, the polka-dot-PJ-clad singer follows a portal that leads him to other beds in an art gallery, a restaurant, a theater box, and a giant one that cruises through London midday traffic.
  
  Bradley and Pablo also shot the clip for Styles' "Watermelon Sugar" single.
