Ms Hilton shared a picture of herself wearing a monochrome cropped top and a pair of black knickers on Friday (24 October).
Looking good, Paris!
As well as showing off her incredibly toned bod, Paris has been busying herself getting ready for Halloween.
Posing with a mask on Saturday, Paris told her Instagram followers: "Can't wait for Halloween!"
She's made sure her house is completely kitted out with all the essential decorations for the festivities.
Paris, 33, has a giant blow-up Frankenstein's monster, tombstones and a petrifying red-eyed woman in her garden. Argh!

The gorgeous DJ and heiress said on Friday: "Finally had my Halloween decorations put up today. #TrickOrTreat."
And she isn't the only member of the Hilton clan getting excited about Halloween this year.
Her adorable pooch Prince Hilton The Pom has been trying out a variety of doggy costumes for the special occasion.
Earlier in October Paris asked: "What should @Prince_Hilton_The_Pom be for Halloween this year? Do you like his hot dog costume?"
Erm… Yeah we do! #adorbs
