Rose -- who became somewhat of a celebrity after dating Kanye West from 2009 to 2010 and even posed nude with the rapper/producer in a '09 Louis Vuitton ad campaign -- was spotted side stage while the 23-year-old performed 'Black and Yellow' before the kick-off to the Steelers vs. Jets game at Heinz Field. Although the performance was not televised, Khalifa, who previously campaigned for the single to be the official Steelers anthem, was honored to take the stage in support of the team. In an email sent to MTV News, Khalifa described taking the stage in the stadium as "awesome" and a "dream come true." In what turned out to be a close game, the Steelers defeated the Jets 24-19.
"I've always had that Pittsburgh pride," he said in a statement, of the motivation behind the song. "I just wanted to let people know where I'm from and represent any way I can and what better way than through our colors. I took that hometown pride and put it in a song."
The Steelers will head to Super Bowl XLV, where they will face off against the Green Bay Packers February 6, at the Dallas Cowboyís Stadium in Arlington, Texas.
