If for some reason you don't know who Rebel Wilson is, you should!
The 26-year-old Australian funnylady cracked us up as one of Kristen Wiig's roommates in Bridesmaids and made us laugh some more playing a children's store clerk opposite Elizabeth Banks in What to Expect When You're Expecting.
And just around the corner is Pitch Perfect, in which she plays a member of an all-girls college a cappella group.
"I've done a lot of musical theater," Wilson tells us of showing off her vocal chops in the Jason Moore-directed comedy. "Of course, I'm not like some pop singer or anything, but I know how to belt it out."
Brittany Snow, who costars in the Universal Pictures movie as one of Wilson's fellow singers, says she's as funny offscreen as she is on.
"She just made us laugh the entire time," Snow gushes. "And basically everything she does in the movie is improvised. She'd just go on these tangents for 20 minutes, and we'd just stand there in awe because she never stopped. So about only one-tenth of what she actually did wound up in the movie. Hopefully they'll put [the rest] on the blooper reel."
And leave it to someone like Wilson to interview herself—well, her hip-hop alter ego Rebellicious—in Bullett magazine.
In the piece, she explains to Rebellicious that she's actually talking to her to prepare for a new film.
"I'm currently researching for a new movie about an interviewer who goes undercover in the rap world only to discover that she herself might have what it takes to be a rap artist even though she's white and her parents are preachers and her only friend in the world, a cat called Tishy, contracts feline AIDS," Wilson says. "Costarring Channing Tatum."
We would so watch that movie.
Pitch Perfect is in limited release in theaters Sept. 28 and opens wide Oct. 5.
