Lachey and his wife, Vanessa Minnillo Lachey, are doing publicity for the new Netflix reality dating show, “Love Is Blind,” which they are hosting.
Lachey and Simpson split in 2005, after three years of marriage. She has written about their relationship, which began in 1998, in her new memoir, “Open Book.”
Lachey told “Today” that there is “definitely a mutual respect” between him and Simpson.
“Obviously, it was a long time ago,” he said. “We’ve all moved on.”
“Open Book” is on sale Tuesday.
