Justin Bieber's mansion has 13 bathrooms & 15 bedrooms in London! It is one of the most expensive houses in the city! It also comes with 2 pools, tennis courts, gardens, a movie theater, a wine cellar & more! Could you imagine trying to keep that place clean?! Yo Biebs, can I come visit?! I am just in awe of this. This house must have its own zip code or something!
