Only a few months ago Kylie Jenner spent $6 million on a Los Angeles mansion, and bought the house next door for a cool $4.5 million. Now Jenner reportedly spent $12 million for a house in the Hidden Hills neighborhood, according to Trulia. That's three mansions before she's even turned 21. Her newest acquisition is a Cape Cod-style house with eight bedrooms, 11 bathrooms, and 1.4 acres of land. The home also includes a home theater, swimming pool, game room, and a spa. It looks like there's no reason for the Keeping Up With the Kardashians star to ever leave her home!
