Spears also posted a message to her fans on Instagram. Below a short video her performing on stage, Spears wrote, "Devastated. My ankle still isn't healed up & I have to reschedule tomorrow's show. I miss this so much & all of u!"
But the singer isn't planning on letting her fans down. Although three shows have been cancelled, Planet Hollywood announced that over 20 additional performances have been added, stretching her residency to the end of 2015.
