The never-shy 'Wrecking Ball' singer showed fans the results of her day in the Tampa sunshine on Thursday (20 March). Ouch!
She added the caption: "Quick change today is gonna be a realllllllllll bitch (sic)."
(Anyone else quite surprised to see she was actually sunbathing in a bikini top?!)
The sunburn picture comes the day after Miley showed fans a nasty looking bruise on her bum - striking a rather raunchy pose in her bikini just to make sure we could see it properly.
It's been an eventful week for Miley, who saw one of her 'Bangerz Tour' buses go up in flames while travelling between concerts on 17 March.
The bus was reportedly carrying the star's mum Tish and sister Noah but thankfully no one was injured in the blaze, believed to have been caused after a tire burst.
