By all accounts, Taylor Swift is great pals with the Haim sisters Este, Alana and Danielle.
So much so, that she posted a (presumably old) video clip yesterday of herself and the trio singing Faith Hill's hit 'This Kiss' as they travelled together in a car.
The occasion was Este Haim's 29th birthday, with Swift posting the video with the message: "Happy Birthday, Este!! Ever since you, Alana, and Danielle adopted me into your wolf pack, life has never been the same."
Nice to see that T-Swift does that OTT head-grabbing dance move even when she's not singing along to other people's songs at awards ceremonies.
Watch the clip below:
