"Today I begin my 26th year of freaking out over stuff," she captioned the throwback snap that showed a mini Taylor making a shocked expression as she rocked a Little Mermaid sweater dress.

Hmm, we think we've seen that face a time or two before…

Always thinking of her fans, the pop star decided that for this birthday, she was going to be the one to give out a gift.

"Thank you so much for all the birthday wishes! I have a little surprise for you," she caption a video posted to her 58.7 million Instagram followers on Sunday. "The 1989 World Tour Live Directed by Jonas Akerlund Released on @applemusic December 20, 2015. More to come soon!"

The 1989 World Tour LIVE
was filmed in front of 76,000 fans at her Nov. 28 show in Sydney, Australia, and features footage from the full concert, plus moments backstage and during rehearsals, which you can see in the trailer below. Apple Music subscribers will be able to download it beginning next Sunday -- as in just in time for Christmas. Well played, Swift!

Teaming up with Apple Music for a concert film is a total Swift move. As many may recall, Apple is the same company the singer had major bad blood with earlier this year -- and the pop star is known for very publicly putting feuds to bed.

In June, Swift wrote an open letter to the company on Tumblr, criticizing their three-month free trial offer for their streaming music service. "I am on my fifth album and can support myself, my band, crew, and entire management team by playing live shows," she stated. "This is about the new artist or band that has just released their first single and will not be paid for its success. This is about the young songwriter who just got his or her first cut and thought the royalties would get them out of debt."

The feud was later resolved, with Swift announcing that she would put 1989 on Apple Music after the company updated their policy.

As fans took in the exciting news, Swift's celebrity friends sent her birthday wishes on social media. See some of the loving posts below.
