Last night, M.I.A. rifled off three quick posts on her Twitter: "BANNED FROM LEAVING THE U.S, FAMILY BANNED FROM COMING TO U.S TO SEE ME, BABY, RECORDING LP, SIGNING THE DOPEST ACTS THATS HITTIN 2010," "I THINK IM READY," and "JUNE 2010."

Which seems to suggest the U.S. government still believes she's some sort of threat and that her much anticipated third album is coming out in June. Either that, or she just really likes the month of June and wants to tell people about it. (She also posted a link to photos from a Jeremy Scott fashion show, saying "IRANIAN PRINCESS SADE IS SPREADING.")

M.I.A. worked with producers Diplo, Rusko, Switch, Blaqstarr, and Sleigh Bells' Derek Miller on the LP. (Could the currently label-less Rising duo Sleigh Bells be one of said "DOPEST ACTS"?) Last week, Rusko Tweeted that the album is finished. And she posted a version of new song "Space Odyssey" on her Twitter last month. More info as we get it.

MP3:> Rihanna: "Rude Boy (Diplo Rudeboyz Remix)"

Yesterday, Diplo took to his Twitter to point out the obvious similarities between Rihanna's new "Rude Boy" video and M.I.A.'s "Boyz" video. But the similarities don't end with the videos, which Diplo made all the more obvious when he posted something else on his Twitter: A blend of "Rude Boy" and "Boyz". They fit pretty naturally together! Click above to stream or download it, via the Fader.

Diplo's Twitter has seen a whole lot of action over the last day or so, including a running dialogue with the dudes from Vampire Weekend.

Diplo to Ezra Koenig: "dude are u gonna sing on major lazer 2 or what?"

Ezra to Diplo: "YES, as long as i can be a villain called Patagonia Killer".

Rostam Batmanglij to Diplo: "will you model for the cover of VW LP3?"

Diplo and Thom Yorke, together at last! On the new EP coming down the pipeline from Diplo and Switch's dancehall project Major Lazer, Yorke will contribute a remix of "Jump Up", the kinetic Leftside/Supahype team-up from last year's Guns Don't Kill People-- Lazers Do album.

MP3:> Major Lazer: "Sound of Siren [ft. Busy Signal and M.I.A.]"

UPDATE: Turns out this is actually a new Major Lazer track! According to Diplo, it's from a new EP.

M.I.A. is a woman without a genre, but her global polyglot pop style has always drawn a lot of inspiration from Jamaican dancehall reggae.

As the Fader points out, "Sound of Siren", a new track from dancehall wildman Busy Signal, features what sounds like a heavily Auto-tuned M.I.A. singing the hook while sound effects erupt all around her. The track appears on the new Busy Signal mixtape Hottt Ed Turf!!!.

We haven't confirmed that it is, in fact, M.I.A., but it sure sounds like her!
