The pop superstar returned to her Disney days as part of the Mickey Mouse club (Justin Timberlake and Christina Aguilera were also members!), by donning a costume from the popular cartoon film, Snow White and the Seven Dwarfs.
And she even encouraged her backing dancers to dress up too!
Britney, 31, posted a cute snap of herself lying down on the floor in a dance studio yesterday (31 October) and wearing Snow White's distinctive yellow and blue dress. Although, her frock was a little more raunchy than the original, as the hem came above her knee.
She also concealed her trademark blonde hair under a black bob cut wig.
The picture shows Britney surrounded by her dancers, who she recruited to be her seven dwarfs and they can each be seen wearing beanie hats that bear their individual dwarf names: Doc, Grumpy, Happy, Sleepy, Bashful, Sneezy, and Dopey.
The chart-topping singer then posted another Brady Bunch style photo, in which all of her dwarfs can be seen up close.
She wrote beside the snap: "Happy Halloween everyone!"
Britney has already got into the Halloween spirit this week by filming a fun spoof video with Radio 1 DJ, Nick Grimshaw.
The video is called 'It's Britney Witch,' playing on Britney's signature catchphrase, 'It's Britney, b*tch', and see the pop star sat on a spooky set and reading out the monologue from Michael Jackson's hit track, 'Thriller'.
Even though Britney is currently occupied with rehearsals for her upcoming Las Vegas residency, we can imagine that she also too some time out yesterday to take her sons, Sean and Jayden, trick or treating.
