The Paddington In Peru star is here just when we most need her.
The Oscar-winning Titanic star was a surprise addition to the festival's line-up on Sunday.
“I’ve always dreamed of being on the show one year and I’m so excited to be on this year’s Christmas Special."
And not a sequin in sight.
It sounds like CBeebies might have a few more grown-up viewers than usual next week.
The Strictly Come Dancing champion will be the first celebrity to tell a story using British Sign Language.
And yes, he's bringing his French bulldog Blue along with him.
"This is me, I am George. I can’t wait to be your friend.”
