The Office star John Krasinski and actress Emily Blunt are engaged, People reports. The couple have kept it low-key, showing up at this year's SAG Awards separately and dating far from paparazzi in Los Angeles. "It's not about celebrity or not," Krasinski, 29, says of his relationship with Blunt, 26. "It's all about, do you have that 'girl in a cardigan' in you. You gotta have that."
