Mariah Carey has no clue as to how many bathrooms she has.

And they say stars are just like us......
US:
Mariah Carey is living the life. Her 12,000 square foot triplex in NYC’s Tribeca district is so big she doesn’t know how many bathrooms she has.
“I don’t know! Do you really want me to try and think about it?” she says in the new issue of Glamour magazine.
The 37-year-old singer has an entire bathroom dedicated to Hello Kitty. “I’ve liked Hello Kitty since I was little,” she says.
