John Krasinski says he was nervous proposing to Emily Blunt — but maybe those unicorns helped.

"We were here in L.A., and there were unicorns and oceans and clouds," the Office star joked to Access Hollywood about his engagement. "She said yes!"

Krasinski popped the question to Blunt last month after nine months of dating. The Devil Wears Prada star was moved to tears by the proposal — and she wasn't the only one."It was very casual. I was nervous and the whole nine yards," Krasinski said. "She did cry after I cried, and we cried and then everyone around us was crying. Then, I think, people weren't really sure what was going on, but they were crying because we were crying. But it was great. At the end of the day, she said yes, which is great. It's a big part of this whole thing."

The two have not set a wedding date yet, nor have they laid out a timeline for starting a family. "Not soon. I think we're going to take our time with that, hopefully," Krasinski said.
