Madonna knows you're wanting, needing, waiting for her...to justify your love. (And also your depleted bank account.)

And today (September 9), six months after wrapping up filming on the final two shows of her Rebel Heart Tour down in Sydney, the #UnapologeticBitch herself provided a brief update regarding the accompanying tour film on — where else? — her selfie-filled Instagram.

"Finally watched a rough assembly of Rebel ❤️ tour and happy to say it should all be finished in 2 months!!🙏🏻💘💃🏻👑. Time to go to WORK!! Thanks to all my fans for being so patient 😘❣," she wrote. Time goes by...so slowly, indeed.

Madonna's Rebel Heart Tour spanned over seven months, brought in over $169 million in revenue, with over a million tickets sold. Within its 20 country, 80+ show run, the Rebel Heart Tour brought Madonna to Australia on tour for the first time in 23 years. The tour also extended her record as the highest-grossing solo tour artist ever — a fittingly historic run for the Queen of Pop.

Here's hoping she keeps the Instagram filters off the final product.
