Traditionally, F1 drivers in Secret Santa give each other Christmas presents. Max Verstappen was assigned Valtteri Bottas. The Dutchman gifted the Alfa Romeo Racing driver a book, but not just any book. He gave 'Museum Bums: A Cheeky Look at Butts in Art', a book of buttocks from the art world. Over all of the existing photos, he pasted a picture of Valtteri's head, a reference to the nude calendar the Finn launched for charity. Watch Bottas unwrap the book above.
