We’ve dropped some awesome collabos on you in the past, but here’s an atomic bomb strapped to a hydrogen bomb. During his final “Welcome 2 America” stop at Madison Square Garden last night, Prince brought opening act Cee-Lo Green back on stage for a rendition of the Gnarls Barkley gem, “Crazy”. The performance, however, was just the piÃ¨ce de résistance of an amazing evening. Earlier that night, Kim Kardashian herself froze in fear of the Purple One’s touch, prompting the Artist to boot her off stage before the two could enjoy what undoubtedly would be the most sensual and akwkward tango ever (if only it were that easy to get rid of Karddashian in all aspects of life). Check out “Crazy” above; it’s a much more satisfying Prince collaboration than other recently proposed partnerships, that’s for sure.
