Jonathan Groff Interviews Lea Michele About Spring Awakening, Cory Monteith & Louder

Jonathan Groff and Lea Michele know there's nothing like a best friend. The stage and screen stars met almost 10 years ago "in [a] dark building in Chelsea" when they auditioned for the off-Broadway premiere of Spring Awakening and the rest is, as they say, history. Michele went on to star as Rachel Berry in FOX's Glee and will soon become a pop star with the release of her album Louder, and Groff is the star of HBO's new buzzworthy series Looking. In the March issue of Teen Vogue (on shelves February 4), Groff got his BFF to open up about their "crazy" friendship, the loss of Cory Monteith and more.

Even though Michele had to "simulate sex more than 1,000 times onstage [with Groff] in Spring Awakening," she confessed that, at this point, she probably couldn't even kiss her hunky friend without chuckling. "I don't think I could. I really think I would laugh too hard," she told Groff. "Whereas we used to make the hell out." Another reason she might be afraid to lock lips with Groff? He might puke. There was that one time... During the hayloft scene, where we always open-mouth kissed. I had the stomach flu and I was going to vomit in your mouth," Groff told Michele. "You opened your mouth and I was like, 'Nuh-uh.'"

Yuck. However, Michele did reveal that Spring Awakening was the "greatest experience of [her] life" because it was how she came to meet her best friend. "In this lifetime, if there is anything you need, it's a best friend," she told Groff. "You believed in me a lot." Michele and her Glee co-star Cory Monteith began dating around February 2012, and, of course, he became one of her biggest champions before he died in July 2013. "My relationship with Cory made me feel like I could reach for the stars and more," she said. One of those stars? Recording her album Louder. "He would be like, 'You're going to be a pop star!'"

Michele told Groff that Louder, which is scheduled to be released on February 28, gets its name from her big personality. "Louder is like me. I'm loud, I come from an Italian family, I don't stop talking," she said. "My favorite song is, 100 percent, 'You're Mine.' I listened to it the other day—it was the one song I had the most emotional reaction to, just because that's my relationship with Cory." Groff told Michele that he believes she is the "quintessential role model" because of how she has handled her work, success, friendships and relationships over the last few years. "As your friend, I saw you exhibit so much strength."
