Taylor Swift is due to arrive on Sydney shores next week ahead of her upcoming concert tour. We take a look at the acts most likely to join her on stage: 
1. Vance Joy 
As the pre-show act for Taylor's Australian leg of her 1989 tour, it is possible that she will invite him on stage during her shows which kick off in Sydney on Saturday,   November 28.

2. Guy Sebastian
Swift and Sebastian have previously worked together during the Red Tour in   December 2013 and he could potentially be asked back to perform on this tour.

3. Tame Impala
As one of Australia's biggest new acts, Tame Impala may be invited to perform on the 1989 tour. Taylor's close friends in band Haim covered the Tame Impala song Cause I'm the Man a few months back. Although their psychedelic style of music doesn't fit Taylor's typically pop sound, anything is possible and Swift might just decide to shake it up a bit in her Australian shows.

4. Troye Sivan
Troye recently dropped his album WILD and Taylor clearly took a liking to it, sharing a picture of her listening to his successful first single with her million Instagram followers a few months ago. Perhaps we'll see them performing the hit song together on stage. 
Vibes. Mood. Feelings.

5. Lorde
???It is no secret that Taylor and New Zealand singer Lorde are close friends and as the Kiwi songstress spends large amounts of time in Australia, Taylor could easily decide to incorporate her in a performance in Australia.
