Taylor Swift declares that she’s the ‘4th Haim sister’ as she teases remix of their song Gasoline

Taylor Swift has had a busy year, releasing two albums, with another on the way.

But the 10-time Grammy winner still has time for some collabs, recently working with some famous friends.

She declared that she’s the ‘4th Haim sister’ Thursday, as she took to her Instagram Story to tease her remix of the sister trio’s song Gasoline, which appears on the new expanded edition of their third studio album Women In Music Pt III.

The 31-year-old posted a video of the middle Haim sister Danielle Haim, 32, lip-syncing along as she listened to a playback of the remix, which dropped Thursday with the expanded edition.

‘When you’re lying between my legs, it doesn’t matter,’ Danielle sings, as Taylor croons: ‘Strike a match, strike a match, watch it blow.’

Taylor wrote with the video clip: ‘Cancel the DNA test I’m the 4th Haim sister and this song is the only proof I need.’   

The sisters wrote of the collab on Instagram: ‘since we released wimpiii in june, taylor had always told us that gasoline was her favorite. so when we were thinking about ways to reimagine some of the tracks from the record, we immediately thought of her.
