Britney Spears is hard at work shooting her latest music video for "Work B*tch", and the pop princess decided to show off her hot bod in between takes!

Donning a blue bikini that showcased her flawless physique, the chart topper shared this sexy snapshot on her Facebook page with the caption, "Gonna get my tan on in the desert in between shots on the #WorkBitch set today. It's HOT out here people!!!! #desert #heatwave."

The tune is rumored to be a sample of RuPaul's hit "Supermodel (You Better Work)", and we can't wait to hear it!

We also can't wait for the blonde beauty to fill us in on her upcoming Las Vegas residency during a scheduled GMA appearance on September 17.
