Demi Lovato greets her fans waiting outside her hotel on Monday morning (April 28) in Rio de Janeiro, Brazil.

The 21-year-old singer is in town for her Neon Lights Tour and she tweeted about something that is happening to her legs!

“Btw – when I’m not able to see a chiropractor for a while, one leg can get up to 1.5-2 inches shorter than the other!!!! #funfact,” Demi tweeted.

“I had a dream last night that a bunch of people dressed in penguin costumes were having a dance-off on the roof of a building next to me…” Demi wrote earlier that day.
