A new pop feud has erupted between Lady Gaga and South African rap act Die Antwoord after the trio killed off a double of the pop superstar in its latest video.

A man dressed in Lady Gaga's infamous meat dress is ridiculed, massacred by African rebels and mauled to death by a lion in the promo for Fatty Boom Boom - and the Paparazzi hitmaker is far from amused.

In a post on her Twitter.com page on Wednesday (17Oct12), Gaga took aim at the provocative South Africans, writing, "i fink u freaky but you don't have a hit. hundred thousand tickets sold in SA. #thatsmys**t... 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 (fan)".

Die Antwoord quickly responded with the tweet, "lady... even tho (though) u r 'larger' than us... we still cooler than u... plus we don't have prawns in our private...(sic)".

The final comment was a reference to a scene in the Fatty Boom Boom video, in which a gynaecologist removes a prawn from the fake Gaga's genitals - presumably a joke about past stories suggesting the singer is a hermaphrodite.

It is not clear why Die Antwoord took aim at Gaga in the video but bandmate Yo-Landi Vi$$er revealed earlier this year (12) that she had turned down the chance to tour with the Poker Face hitmaker.
