Olivia Rodrigo’s Deja Vu co-written by Taylor Swift, Jack Antonoff and St Vincent

Taylor Swift, Jack Antonoff and St. Vincent have been credited as writers of Olivia Rodrigo’s ‘Deja Vu’.

The ‘good 4 u’ hitmaker’s metadata for the ‘Sour’ single changed on streaming services Spotify and TIDAL to include the three artists.

Olivia, a die-hard Swiftie, recently revealed Taylor’s song ‘Cruel Summer’ inspired ‘Deja Vu’.

She explained: “I wanted [the bridge] to be really high energy because the rest of the song is very serene and eerily calm.

“But I wanted the last bridge to kind of go crazy and I love ‘Cruel Summer,’ it’s one of my favorite songs ever. I love the harmonised yells she does. I feel like they’re super electric and moving, so I wanted to do something like that.”

Taylor, 31, and Jack, 37, are both credited on the 18-year-old pop star’s track ‘1 Step Forward, 3 Steps Back’, which features a sample of the former’s song ‘New Year’s Day’ from 2017’s ‘Reputation’.

Jack co-wrote and co-produced the song with the ‘Shake It Off’ hitmaker.

Meanwhile, Olivia recently revealed she would love to feature on Taylor’s re-recording of ‘Speak Now’.

The music star revealed the US megastar’s 2010 record is her “favourite” of her back catalogue, and after the likes of Keith Urban and Maren Morris featured on previously unreleased tracks from Taylor’s vault for the re-recording of her 2008 LP ‘Fearless’, Olivia has put it out there that she’d love to duet with her idol.
