Two names that you may not expect to be heard together in a feud would be M.I.A. and Anderson Cooper, but they are.

On Wednesday night, M.I.A. tweeted her fans to watch a new documentary, Sri Lanka's Killing Fields.

Someone should make @AndersonCooper watch it / film it and show the world what happens when respected journos get it wrong.

@AndersonCooper called me a terrorist for speaking out, and expressed support for the SLgov when this was happening.

Cooper seemed a bit confused by M.I.A.'s tweets and responded, What are you talking about? You are mistaken. I never called you a terrorist. I don't even know who you are other than the lady who sang at superbowl...By the way, I defended your finger pointing at the superbowl, so check your facts. I've no idea what youre tweeting about.

M.I.A. went on to explain to Cooper why she was singling him out.

In 2009 u linked to a article that was written about me with false info. there was a rebuttal on ur 360 site...2 months later 1ce every tamil had been silenced including me, the SLGOV carried out the killing of 40, 000 civilians.

M.I.A. is Sri Lankan and has been vocal in her support of the Tamil Tigers.

You've gone from saying 'I wrote', 'I called you,' to saying my cnn show blog had a link to an article, Cooper responded. Big difference...we link to many articles with different viewpoints, and we gave you an opportunity to respond. I can understand your frustration if someone wrote untrue things about you, and I'm glad you were able to respond.

Cooper and M.I.A. seemed to end their feud on a good note.

The brutal war in SL has not gotten enough coverage in the US, and I know that's very upsetting, Cooper continued.

 I'm glad u understand but please watch #killingfield because this is what i was trying to say, M.I.A. tweeted.
