NEW YORK » Taylor Swift is releasing a live concert special from her star-studded “1989 World Tour” exclusively on Apple Music.

The pop star announced today, on her 26th birthday, that she will release the “The 1989 World Tour LIVE” on the streaming platform on Dec. 20. It will not be available for purchase, but it is free for streaming for Apple Music users.

The concert features Swift’s performance taped in Sydney, Australia. It will also include special appearances from Justin Timberlake, Mick Jagger, Kobe Bryant and others.

Apple Music is currently the only platform streaming Swift’s “1989.” Swift, who wrote a critical Tumblr post in June about Apple’s initial decision to not pay artists during its free trail launch of Apple Music, said Apple contacted her about capturing one of her concerts.
