Wiz Khalifa -- So What I Bought a New House ... DEEP in Steelers Country

Rapper Wiz Khalifa loves black and yellow so much, he just put down some MAJOR roots in Steelers territory -- with a brand new $900,000 Pennsylvania pad.

The sleek, high-tech, 5-bdrm, 4-bath house in Canonsburg, PA is 3,891 sq. ft. of Brazilian wood floors, modern décor and bad ass lighting.

The rap giant didn’t skimp on amenities either -- with stainless steel appliances, swanky granite tops, 15-ft ceilings, and a ginormous outdoor entertainment patio.
