She said: "My family dynamic probably plays a really big role in why our relationship has just worked and it's because when I was born, my oldest sister was 17 years old, Mike (her husband) was 16 years old, my brother was 15 years old.
I always hung out with my grandpa and older cousins., older sister and parents.....there were no kids my age, just a couple younger BUT I always acted more mature.".
Jess, from the US, explained that her stepdaughter was just eight years her junior, and first met when she was 18 and her stepdaughter was 10.
In another video, Jess responded to a comment that claimed her relationship was weird for the 16-year age gap she and her husband have.
Jess also added that her parents were both older when they conceived her, so she always got on better with older people.
