Sharon bought the light brown faux fur number with a knitted trim ahead of the cooler weather and she thinks it's the bees knees. But Kelly...not so much!
The X Factor judge even put the hat on Kelly's head in an attempt to convince her that it is the way forward when it comes to keeping warm.
But sharing a picture of herself on Instagram, Fashion Police host Kelly commented: "My mum bought this ridiculous hat and keeps trying to justify its coolness to me but it's not working!
"P.S. don't judge me I have make-up on!"
Kelly received several comments from fans, however one made great sense.
The follower told Kelly: "It's cool if you're en route to the stylist and don't necessarily want people to see your hair at the moment. It's cute."
