Lachey noted everyone acted respectfully. His family was on the flight; Simpson sat next to her mother while her partner and children were in other seats. PEOPLE had earlier reported the group shared a pleasant, polite conversation that included Lachey’s wife, Vanessa.
The pair, married from 2002 to 2006, remain linked in memory: Simpson called Lachey her "first love" in her 2020 memoir Open Book. Lachey later wed Vanessa in 2011; they host Netflix dating shows Love Is Blind and Perfect Match and have three children. Simpson separated from Eric Johnson in January 2025, with whom she shares three kids.
