Kacey Musgraves has broken a rib after suffering a fall in Mexico

Alongside an image of her X-ray, Kasey wrote on Instagram: "Sooo I'm in Mexico with a f****** broken rib.

"Wednesday night it was raining and I was running to grab some towels and had an extremely hard fall on some very slick tile I didn't see. Thankful I didn't smack my head but I landed very very hard on my back left ribcage, and I broke rib number 6.

"This s*** is no joke. I'm in a lot of pain and doing ANYTHING is extremely difficult but I'm managing and being well taken care of. (sic)"

Kacey is currently unable to perform live because of her injury. The singer has also been forced to reschedule the live recording of a podcast.

She continued: "There is no physical way I can get on a plane and fly back to Nashville for the @singforscience event with @paulstaments on Sunday at @theryman. I am extremely bummed to have to reschedule as I have been looking forward to this for months but there is literally no other option. I'm so sorry for the inconvenience. (sic)"

Kacey released her debut album, Same Trailer Different Park, in 2013, and she's subsequently become one of the biggest names in country music.

The singer - who was born and raised in Texas - recently revealed that she loves taking her music overseas and engaging with her international fans.

The Merry Go 'Round hitmaker told The Hollywood Reporter: "I'm going to South America, then Asia and Australia.

"I'm playing Brazil for the first time. I know the energy and the fans there are unlike anywhere else. I'm playing this massive rodeo [Sao Paulo's Jaguariuna], which is really cool. Rodeo is huge in Brazil.

"It's been really cool to see the rest of the world come to love country music, because, really, country is more about a mentality and an attitude versus geography. Real country music is based on real emotions all humans have, no matter where you're from."
