Now that's a reunion!
But don't worry, it's all for film!
We'd hate to see anything happen to our precious Zac Efron's gorgeous mug.
And luckily for us, nothing has, but he did let his film crew make it quite a mess for the filming of We Are Your Friends.
Zac's poor face was all scratched up and bruised for some scene that must be quite intense!
While we're not digging that particular look, we are digging him all sweaty in other snaps (above).
Maybe he can come over later and we can give him a nice shower to wash all that grim off! LOLz!
