For “808s & Heartbreak”‘s third video, Kanye West has enlisted the help of labelmate Rihanna.  The singer has made a few public appearances since her alleged beating at the hands of boyfriend Chris Brown (whose recent video blog touting his new album I won’t dignify with more than a sentence here), but this is the first connection to a musical event she’s had since the Brown incident. I can’t say that the video makes a hell of a lot of sense, but Ri-Ri sure does look good. What do y’all think?
