Musician tweet of the week: Ke$ha

I gave John Mayer a lifetime exemption from douchebag status after his moving instrumental version of "Human Nature" at Michael Jackson's funeral, but after some of the recent interviews Mayer has given I've been forced to rethink that.

Last week Mayer tweeted to Ke$ha, seemingly innocently: "Dear Ke$ha, you have won me over with your tricks and charms and I must tell you I really like your song."

Ke$ha responded:

dear john mayerrr. Don't be a little b*tch wit ur chit chat. Jus $how me whur ur dick's at. x
