Opposites attracts, John Legend admits to being different from his wife

“We were always different,” the songwriter John Legend recently told PEOPLE. “I was always a little bit more buttoned up, and she was always more brash and free.”

Legend went on to admit that Teigen‘s outspoken nature took a bit of getting used to. “I would get a little nervous at first with some of the things she would say, because I didn’t know how people would react. I usually played it more safely,” he shared. But ultimately, Legend said, the spouses of four years found strength in their differences:

“I think she’s brought me out of my shell a bit, and made me enjoy life a little bit more. It’s been fun to grow together in that.”
