— -- Nearly 2 million fans have seen Taylor Swift's "1989" world tour. If you haven't, now you can.
The pop superstar and Apple Music are teaming up to bring fans "The 1989 World Tour LIVE" film. It's not only a concert; it's a look inside her world, with never-before-seen backstage footage.
In the film, Swift talks about reaching out to fellow musicians to appear on her tour.
"I wondered what would happen if I invited some of the most amazing artists in the world to come out with me and perform on my stage -- would they do it?" she said in a trailer from the film.
Some musical guests on Swift’s tour include Justin Timberlake, the Weeknd, John Legend, Leona Lewis, Keith Urban, Mick Jagger, Pitbull and Mary J. Blige.
A Swift show wouldn't be complete without her squad -- so Gigi Hadid, Kendall Jenner and Karlie Kloss all make appearances.
"It would be weird to not include my friends –- these were the people who helped me get to this point where I could make this album," Swift says in an exclusive clip from an interview with Apple Music Beats 1.
Apple Music Beats 1 radio station's Zane Lowe will air its full interview with Swift on Monday, December 14 at 9 a.m. PT from Sydney, Australia.
Members of Apple Music will be able to watch the film when it debuts on Dec. 20.
Swift, who turned 26 on Dec. 13, tweeted a trailer of the film on her birthday to her 67 million fans.
"The 1989 World Tour LIVE" was filmed on Nov. 28 in front of 76,000 fans at the ANZ Stadium in Sydney.
