Speaking to another of the exclusive Swift set, Lorde, as part of an interview for U.S. magazine Dazed & Confused, Dunham reveals the Love Story singer is such a great "camp mother" and she appreciates her pop star friend when it comes to getting the girls together.

The actress says, "I feel that Taylor has really taken control and said, 'I'm going to get us all together in the same place, I'm gonna make it very clear that friendship is powerful and women are magic and if anybody thinks this is a witches’ coven they might be right'... She’s just made it her job in a very cool way."

Lorde agrees and admits she likes the fact Swift is accepting of all her pals: "She definitely brought me into this amazing world of supportive female friendship. For me, someone starts talking about boys and I'm like, 'I just don’t know what to say'. I'm useless in that capacity and that was why I thought, 'Well, I can't have girl friends (because) I don't know how to talk about boys'.

"But Taylor just glosses over the fact that I'm terrible at that and she’s just like, 'It's OK, I'll love you for your other qualities'."

Joining Lorde and Dunham in Swift's inner circle of friends are Karlie Kloss, Selena Gomez, Jaime King, Hailee Steinfeld and Gigi Hadid, many of whom appeared in the singer's star-studded Bad Blood video.
