First things first: Happy birthday, Taylor Swift. Grab Kendrick Lamar for another song-improving verse soon. To celebrate her day of birth, Taylor announced the Apple Music exclusive documentary 1989 World Tour LIVE documentary and dropped the first trailer.

The press release confirms that this is a decidedly stacked affair by dropping a lengthy list of musical guests, which shouldn't be a surprise for anyone fortunate enough to have witnessed the 1989 tour in person:

Alanis Morissette, Alison Krauss, Beck, St. Vincent, Ellie Goulding, Fetty Wap, Fifth Harmony, Idina Menzel, John Legend, Justin Timberlake, Leona Lewis, Lisa Kudrow, Lorde, Mary J. Blige, Mick Jagger, Miranda Lambert, Natalie Maines, Nelly + HAIM, Nick Jonas, Ricky Martin, Selena Gomez, Steven Tyler, The Weeknd, Walk the Moon, Wiz Khalifa.

Untouchable.

It's probably worth noting that, as recently as June of this year, Apple and Taylor Swift weren't exactly the closest of BFFs. What a difference a few months can make.

The doc will premiere exclusively on Apple Music beginning Dec. 20 right here.
