Although they may have invites to all kinds of hot bashes in Hollywood, the two stars decided to have a relaxing cooking session at home instead last night (2 October) and it looks like they're a dab hand in the kitchen!
Kelly, 28, and Taylor, 23, donned their pretty matching aprons and got to work whipping up some chocolate peppermint cookies along with another friend.
Posting a picture of themselves waiting patiently by the oven, Kelly wrote: "#GirlsNight baking with @taylorswift, you guys have no idea how good Taylor is at cooking! #shocked."
She soon uploaded another snap of the chocolate treats once they'd baked, proving that she and Taylor make a pretty successful team.
Kelly wrote: "Our homemade chocolate peppermint cookies are amazing! In homemade foodie heaven with @taylorswift & @Claire_winter"
The Fashion Police co-host also joked that she, Taylor and their friend had formed a girl group called The Culinary Patience Turtles while bonding in the kitchen. If only!
Given that Kelly's fiancé Matthew Mosshart is a chef, we wonder what he thought of the girls' baking skills?
Matt is thought to have proposed to Kelly last year, although they chose not to announce their engagement until this July.
The couple have remained tight-lipped on the details of their upcoming nuptials, but mum Sharon Osbourne has said that Kelly hopes to get married in England next year.
We wonder whether she'll hire Taylor to bake her wedding cake?!
