Those Aussies tend to stick together -- but one big star from down under had some pretty harsh words for Rebel Wilson.
The hilarious Australian actress was a guest on "The Tonight Show" with Jay Leno on Tuesday, where she revealed one very rough run-in with the sometimes-irritable Russell Crowe.
Check out the video above to find out why he once yelled at her to "F**k off!" Ouch!
Rebel will be hosting the MTV Movie Awards this Sunday -- and last night she teased appearances from James Franco, Brad Pitt and the cast of "Pitch Perfect."
"It's pretty full-on," she says about her hosting gig. "I have to dance, I have to sing, I have to do jokes and I have to try to look hot ... that'll probably be the hardest one."
