"Please come back later... unless you're actually on fire."

The handwritten pink scrawl suggests a level of stress that is entirely understandable for the team putting on the biggest stadium tour of the year.

With 64 sold out shows across North and South America, Shakira has played to more than two million fans.

"I've worked for over a year, polishing every single detail of the show, so this is really an amazing reward," the star tells BBC News.

There are no frayed nerves or screaming matches backstage before the Miami show... and no-one's on fire.
