Die Antwoord, who I love, have released a rather vicious video in which Gaga plays a central role.

Personally I think ones music should speak for itself and if you feel the need to attack another artist it reflects more on you than them. Not to mention the irony of people attacking someone's celebrity in an effort to gain the same for themselves.
I like Gaga's response.
i fink u freaky but you don't have a hit. hundred thousand tIckets sold in SA. #thatmyshit
i guess its not a good idea to tell someone you're a fan. never mind! we get it, you're not a little monster. WE GOT IT.
(That said the Die Antwoord and their song are very good)
