Photo by Kathryn YuBillboard reports (and the show's website confirms) that M.I.A. has been added to the already-jammed roster of performers at this Sunday's Grammy Awards telecast. "Paper Planes" is, of course, nominated for Record of the Year in an uncharacteristic bit of good decision-making on the Grammy folks' part, and the news of M.I.A. getting Grammy-stage shine would be good in any circumstance.But, uh, M.I.A. is nine months pregnant, and she reported in a MySpace blog post last year that her baby is actually due on Grammy night. This leaves a possibility that M.I.A. will give birth onstage. Sunday night's big show already had a truly impressive roster of performers lined up, what with Radiohead's first performance on the show as well as U2, Justin Timberlake with T.I., and the "Swagga Like Us" rap Mount Rushmore team-up of Kanye West, Jay-Z, Lil Wayne, and T.I. (maybe with M.I.A. too?) But this baby thing really pushes it over the top. No way we're missing this show now, whether or not the Lee "Scratch" Perry thing actually happens.
