While watching a documentary about Sri Lanka's war against the Tamil Tigers, M.I.A. thought she'd take on a two year old beef with CNN's Anderson Cooper.
"Anderson Cooper called me a terrorist for speaking out, and expressed support for the Sri Lankan government when this was happening," she wrote on Twitter.
"Someone should make Anderson Cooper watch it/film it and show the world what happens when respected journalists get it wrong."
"M.I.A., you are mistaken. I never called you a terrorist," replied the puzzled Cooper. "I don't even know who you are other than the lady who sang at Super Bowl."
"By the way, I defended your finger pointing at the Super Bowl, so check your facts. I've no idea what you're tweeting about."
"You called me a lady Tamil Tiger when I talked about Tamil civilians dying, and u printed a retraction," M.I.A. fired back linking to an article on the CNN website titled 'Lady Tamil Tiger gives pop culture a bang.'
"In 2009 you linked to a article that was written about me with false info. There was a rebuttal on your 360 site."
The article briefly spoke about the singer's 'Paper Planes' as it said: "To some, M.I.A. is a peaceful revolutionary artist who has shed light on a desperate situation in Sri Lanka. To others she is a LTTE propagandist rousting international support for a terrorist organization. is a song about immigration."
"M.I.A. you've gone from saying 'I wrote,' 'I called you,' to saying my CNN show website had a link to an article. Big difference," Cooper responded. "We link to many articles with different viewpoints, and we gave you an opportunity to respond."
"Two months later, once every Tamil had been silenced including me, the government carried out the killing of 40, 000 civilians," the singer added.
"I can understand your frustration if someone wrote untrue things about you, and I'm glad you were able to respond," Cooper said as he tried to put an end to it.
