Speaking on The HoneyDew With Ryan Sickler podcast, Duhamel, 53, said he was 21 years old when his younger sister, Kassidy, was born. Years later, he noticed that Kassidy and Mari, 32, are almost exactly the same age.
Duhamel laughed as he recalled telling Mari, "You and Kassidy are exactly the same age. Ooof, I am officially too old for you."
The couple married in 2022 after dating for four years. They welcomed a son in January 2024 and a daughter in May 2026.
Mari has previously said their age difference rarely comes up, except when talking about having children. She joked that Duhamel would likely have even more kids if he were younger.
Duhamel also shares a son with his ex-wife, singer Fergie. He has said they remain on good terms and continue to co-parent successfully.
