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. I guess it’s 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.”It is not clear why Die Antwoord took aim at Gaga in the video. Agencies
