Josh Groban Talks Emma Stone Kiss In 'Crazy, Stupid, Love' In GQ

Before Emma Stone can begin that buzzed-about romance with Ryan Gosling, she's got another boyfriend in the film. The lucky (and eventually unlucky) man who loses her? Not your typical Hollywood beefcake jerk, but instead, the unexpectedly hilarious Josh Groban.

Yes, that Josh Groban.

The contemporary classical singer has a supporting role in the film as a lame lawyer with a terrible taste in cakes and celebratory restaurants. No spoilers here, but there is a scene that didn't get included in the movie: his kiss with Stone.

"At the end of one of our scenes the directors came up to us and said, You know, this is feeling a little goofy. Let's just try to make this more believable with a kiss at the end,'" he told GQ. And I'm thinking, Holy sh*t. That wasn't in the script. I've never kissed on camera before. What does that mean? What do I have to do? I didn't take that class in college."

So what happened? Thankfully, his co-star came to the rescue.

"And Emma's just this total pro. She pulls out her lip-gloss, and says, 'It's cherry. That cool with you?" he remembered. "I mean, that kiss shall forever be my deer in 'Stand By Me'; my moment alone, no one will ever be able to treasure it but me."

Lucky guy.

Groban's actually got a number of screen credits to his name, with appearances in "Ally McBeal," and voice work in "American Dad" and "Robot Chicken." He also guest hosted an episode of "Regis and Kelly," which, presumably, did not involve him doing a Regis impression and kissing Kelly. Unless that footage got cut, too.
