She's the in-demand Hollywood star who regularly rubs shoulders with other well-known A-listers.
And Rebel Wilson shared a comedic throwback with heartthrob actor Zac Efron on Friday.
The Australian actress took to Instagram to share a 2012 picture from backstage at The Ellen Degeneres Show, writing: 'Tbt to the legend that is @zacefron.'
Both stars pouted for the camera as they flashed sideways peace signs with the fingers.
Rebel appeared to joke about their former looks, writing: 'We did our hair the same and everything.'
