Rapper Q-TIP has recruited U.S. presidential hopeful Barack Obama to lay down vocals on a politically motivated track for his latest LP. The Breathe And Stop star, who uses Democrat Obama's inspirational voice over hip-hop music on his new album The Renaissance, has also collaborated with soul singer Norah Jones and controversial filmmaker Spike on the political project. The 37-year-old tells the New York Post's Page Six, "I've got Norah Jones on there, but Barack is the big one. You'll see what happens, I can't reveal too much." The hip-hop hitmaker joins former Batman Michael Keaton, Oscar winner Halle Berry, actress Jessica Alba, will.i.am, Oprah Winfrey and Will Smith, all of whom have spoken openly about their support for Obama.
