The DJ and TV presenter was joined for the festive edition of the ITV2 show by Olly Murs, Peter Andre and James Blunt.
She said: "Post Christmas Celebrity Juice. I find myself in a towel turban again. But why?..."
Then Fearne teased on Twitter: "Just finished the Christmas Celebrity Juice special and once again need a LONG shower post show. Find out why on itv2 soon!"
However the star, 32, was obviously loving her new look, as she kept the towel wrapped tightly round her head when she left the TV studios later that night.
She added another snap on Instagram and said: "Taking the turban to new heights. Inspired by Miley."
The following day, Fearne arrived at Radio 1 looking chic as usual.
There was no sign of last night's towel turban, but Fearne was clutching a beautiful bunch of flowers in her hand.
It was her colleague Anna's last day working on Fearne's show, so we guess they must have been for her.
What a sweetie Fearne is!
