Taylor Swift has plans of celebrating like it's 1999 for her upcoming 26th birthday.

HollywoodLife reports the "Shake It Off Singer" is planning to fly boyfriend Calvin Harris and as many as her "Bad Blood" girl squad members as she can to Australia to celebrate with her. Currently in Melbourne performing on her "1989" tour, Swift will be so inclined until Dec. 12, just a day before her born day.

Given such a tight schedule, word is Swift is all in on the idea of booking a private jet to fly all her near and dear to Hamilton Island for the big bash. Reports are that includes the likes of Selena Gomez, Gigi Hadid, Karlie Kloss and Cara Delevingne.

In addition, Swift's who's who guest list could also include everyone from Oprah Winfrey to Ed Sheeran to Justin Bieber and Kendall Jenner.

Indeed, it's quite the time to be Swift, who is also rumored to be growing even closer to 31-year-old, yearling boyfriend Harris. The two recently broke bread with Hollywood star Jason Statham and his model girlfriend Rosie Huntington-Whiteley in Beverly Hills at the exclusive Palm Restaurant.

Reports are Swift and Harris are planning on spending even more time together once her tour had ended.

"They are looking forward to a handful of nights dining in and lounging in pajamas, watching movies and hanging with her cats," said a source. "They want to do the homebody thing and not really go anywhere since she has been traveling for her tour, she just wants to be home with friends and family and of course Calvin."

In addition, In Touch Weekly recently reported the two were contemplating tying the knot in two different celebrations.

"Taylor plans to marry Calvin next year in two different locations--- one in the U.K. that will be a huge, over-the-top blowout party and one in either Nashville or L.A. that will be a little more subdued."
