New squad member! Taylor Swift brings Aussie transgender model Andreja Pejic on stage

Taylor Swift has a new member of her ever-growing celeb BFF squad…and she's an Aussie!

Transgender model Andreja Pejic joined Tay-Tay on stage for her latest 1989 concert in Chicago, dancing alongside Victoria's Secret Angel Lily Donaldson.

That's Andreja in the white dress and thigh-high boots – watch above to see the glamazons tear it up to 'Style'.

It's another big moment for 23-year-old Melbourne-raised Andreja, who became the first openly transgender model to be profiled by Vogue in May 2015.

Taylor tweeted afterwards that her pals "shut down the runway". Welcome to the squad, Andreja…can you get us in?

Taylor has made a habit of drawing in special guests for each show. Lorde flew 19 hours from New Zealand to perform one song at Taylor's Washington D.C. gig last week! Check it out:
