Zac Efron, Miley Cyrus, Aly & AJ, and Emma Roberts go all out for Halloween

We know. You're sitting there, in front of your computer, thinking to yourself, "My Halloween simply isn't complete until I know what Zac Efron is wearing on this glorious autumn evening!"

Okay, fine. That's what we were thinking.

Thanks to his Disney comrades Aly & A.J. Michalka, we've got photo evidence of Mr. Efron's tiny little shorts Halloween finery. "Love our friends xo," they tweeted, along with the above picture of a mustached Efron. Yeah, we bet you do.

The ladies also shared the photos below, with Miley Cyrus and Emma Roberts.
