Nearly two decades after his divorce from Jessica Simpson, Nick Lachey offered a rare glimpse into the experience while co-hosting Netflix's "The Ultimatum: Marry or Move On" with his wife, Vanessa Lachey. While advising a couple navigating relationship uncertainty on the show, Lachey acknowledged the lasting impact of his past divorce, stating, "I understand the hurt, the scars that exist from that." He and Simpson, whose highly publicized marriage and subsequent reality show "Newlyweds" captivated audiences, finalized their divorce in 2006.

Following the divorce, Lachey released the poignant ballad "What's Left of Me," featuring his now-wife Vanessa Minnillo in the music video. The couple's relationship developed more gradually, with Vanessa revealing on "The Ultimatum" that she had once given Nick an ultimatum. She explained, "I kept pointing the finger and I took that finger and I turned it to myself... I had to say, ‘What am I not giving him?’" She admitted to prioritizing her social life while simultaneously expressing her desire to start a family, leading to conflict in their relationship.

Lachey emphasized the importance of not letting the past dictate the future, sharing his own journey toward a fulfilling marriage and family life with Vanessa. He acknowledged that their relationship isn't perfect, but underscored the significance of love, belief, and shared values. This advice comes amidst rumors surrounding Jessica Simpson's own marriage to Eric Johnson, fueled by a cryptic Instagram post in November hinting at personal struggles.
