Who doesn't wanna collaborate with Bun B? Feeling left out, Usher made the call for some street cred and star power for his Versus EP which is an extension of his current album Raymond V. Raymond. Slick talkin' in a broad's ear well enough to get a giggle and a Parental Advisory sticker, he tells 'em everything short of "b#tch get in." And Bun never been an everday Joe like G.
