A s reported last week, Pittsburgh rapper and devoted Steelers fan Wiz Khalifa made an appearance at Sunday night's NFL AFC Championship Game to perform his Steelers-glorifying anthem, "Black and Yellow."

Khalifa emerged in the stands behind the end zone before the opening kickoff armed -- but of course -- with a yellow Terrible Towel. He pumped up Pittsburgh die-hards with a rousing rendition of his tune, leading them in the Terrible Towel Twirl.

The 23-year-old rapper must have done something right -- Pittsburgh defeated the New York Jets 24-19 AND "Black and Yellow" currently holds the No. 5 position on Billboard's Hot 100 chart.
