In the latest installment of the Vlog Brothers, author John Green's vlog series (that's "video blog," for you fogies out there), Green goes behind the scenes with new BFF Cara Delevingne.

Delevingne is, of course, the model-turned-actress who stars as Margo Roth Spiegelman in the upcoming film adaptation of Green's book "Paper Towns." Topics covered -- most with Delevingne answering in the American accent she'll use in the film, natch -- include, but are not limited to, eyebrow quality, bacon, whether "Paper Towns" male lead Nat Wolff is a good kisser and whether Delevingne is, in fact, an octopus. (Spoiler alert, she totally is.)

"He's a good kisser, he's a really good kisser," Delevingne said of Wolff. "I was actually talking about him with a friend of mine who's also kissed him, and we had a whole conversation about he was a good kisser."

Pardon? Who's that friend? Who else has Nat Wolff been making out with lately?

We learned so much today, and yet we have so many questions still. Thanks, Cara and John!

"Paper Towns" hits theaters July 31, 2015.
