Meet MTV Movie Awards Host Rebel Wilson

The 'Bridesmaids' and 'Pitch Perfect' funny lady follows in the footsteps of Russell Brand, Jason Sudeikis and Aziz Ansari.

Wait a minute — did you just say you don't know who Rebel Wilson is? Well, the host of the 2013 MTV Movie Awards is poised to become the next big comedy sensation — although her fans think of her that way already.

As this year's mistress of ceremonies, Wilson follows in the footsteps of an illustrious series of up-and-comers who held court in front of some of Hollywood's biggest stars, including Russell Brand, Jason Sudeikis, Aziz Ansari and Andy Samberg, just to name her four predecessors. But if you're still scratching your head wondering how this adorable, hilarious blonde ended up squaring off against the likes of Channing Tatum, James Franco and others, check out a primer that will give you an overview on all things Rebel Wilson.

She Once Shared The Stage With Another MTV Movie Awards Host

A native Australian, Wilson began her career on the small screen on kiwi sitcoms and in sketch comedy troupes such as Los Angeles' Upright Citizens Brigade. Before she made her way to the big screen, however, she performed with 2012 MTV Movie Awards host Russell Brand at the inaugural Variety's Power of Comedy event. Perhaps their collaboration rubbed off on her?

Through Her Torment, Kristen Wiig Became A Movie Star

Wilson's first major role in a motion picture was in "Bridesmaids," where she played Brynne, the jerky, dimwitted sister of Wiig's character's roommate (played by Matt Lucas). Although her character mostly existed to make Wiig's home life a living hell, she distinguished herself immediately, eventually ranking third among the movie's big breakouts (after Wiig and scene-stealer Melissa McCarthy).

Never A Bridesmaid, But She Did Become A Bride

In 2012, Wilson took the crucial role of Becky in "Bachelorette," a comedy effectively billed as " 'Bridesmaids' meets 'The Hangover.' " Playing bride-to-be to three jealous, troubled friends (played by Kirsten Dunst, Isla Fisher and Lizzy Caplan), she not only held her own against three much more established actresses, she upended body-image conventions by being the only one with a happy, stable relationship despite her full figure.

Unafraid To Play Up Her Plus-Size Physique

Playing a character unflatteringly named Fat Amy, Wilson was the first actress cast in the musical comedy "Pitch Perfect." She not only exuded charisma from the page as the most shockingly overconfident member of the all-girl a cappella group Barden Bellas, she threw herself into the role with wild abandon, almost overshadowing the film's would-be star, Anna Kendrick, as she delivered line after classic line. You can find GIFs on the Internet of virtually everything she says and does in the film.

She Attracts Attention Even In Action Movies

In advance of her hosting gig at the 2013 MTV Movie Awards, Wilson scored a small but stand-out role in no less than the latest Michael Bay movie, "Pain & Gain." The filmmaker is well-known for his appetite for lissome starlets and supermodel types, but even he was wowed by her talent and imagination, having her play the kinky wife of an erection-deficient bodybuilder opposite Anthony Mackie.
