Christina Aguilera has opened up about her raunchy relaxation ritual - she loves reading erotic novels in the bathtub.
The Dirrty hitmaker admits taking a waterproof book into the bath is her favourite way to unwind after a long day recording and looking after Max, her two-year-old son with music executive Jordan Bratman.
She tells Britain's OK! magazine, "I love water-eroticas - waterproof books full of erotic stories, if you will. You can literally get the book wet, read it in the bath."
