From her MTV Movie Award-nominated kiss with Miles Teller in "The Spectacular Now," to her steamy smooch sesh with Theo James in "Divergent," Shailene Woodley's had her fair share of onscreen lip-locks.

But when MTV News recently caught up with John Green on the TIME 100 red carpet in New York, "The Fault in Our Stars" author didn't have much to say about his leading lady's "X's" but quite a bit to say about her "O's."

“The first time we met, we hugged the regular way and then she looked very, very deeply into my eyes from like two inches away -- it's pretty intense -- and then she said, 'I need some heart to heart,' and then we hugged the other way so that our hearts touched," Green said. "And now every time I see Shailene, we hug heart to heart -- it's great. I'm such a huge fan of hers; she's awesome."

In the film adaptation of Green's young adult bestseller, Woodley plays 16-year-old cancer patient Hazel Grace Lancaster. And while he was thrilled to see his story played out on the silver screen -- "I've seen the movie twice!" -- he seemed even more excited for fans to see his hug buddy in action.

"I think that once they see Shai as Hazel and Ansel [Elgort] as Gus, it's just going to feel magical to them, the way it felt for me. So I'm just excited for them to see those two actors bring those characters to life," Green explained. "[The movie] is really, really great and no one is paying me to say that. I really love it. I think it's such a faithful adaptation; I'm so excited about it. It's a great honor to have all of those people share their talents with this story."
