M.I.A.'s Maternity Wear: A Retrospective (SLIDESHOW, VIDEO)

Let's be honest: the real winner at Sunday night's Grammy Awards was rapper M.I.A.'s pregnant belly, draped in show-stopping sheer ensemble during her jaw-dropping performance with T.I., Jay-Z, Lil' Wayne, and Kanye West. And we mention that Sunday was her due date?

31-year-old M.I.A. gave the best pregnant performance we've seen since a nine-month pregnant Amy Poehler brought the house down with her Sarah Palin rap on SNL in October (and gave birth one week later) .

The rapper born Mathangi "Maya" Arulpragasam, who spent her life between London and Sri Lanka, has had an epic year: She's expecting her first child baby with fiance Benjamin Brewer, the son of Warner Music Group Chairman and CEO Edgar Bronfman Jr., her single "Paper Planes" was a hit and nominated for "Record of the Year" at the Grammys, and she worked on the soundtrack for "Slumdog Millionaire," for which she received an Oscar nomination.

Here's a look at the Grammys' "Best Dressed Belly" and all the maternity wear that came before it.
