The producer clearly loves his kids, and he is often seen posting images of himself doting on his sons on his Instagram page. In an Instagram post, AJ Cook shared an image of herself, her husband, and their son, Mekhai hugging themselves in a warm embrace. The image was to celebrate Mekhai's award of kindness, which he got from school.

NATHAN'S FASHION BRAND 

Having a celebrity hubby may tend to overshadow one's achievements, but that is not the case for Nathan Andersen. He has earned a massive fan following of his own on Instagram thanks to his many travel photos. So far, his page boasts of well over 33,000 followers. For a non-celebrity, that is no mean feat! 

Other than traveling, Nathan has shown notable interest in fashion. He owns a fashion brand named "Walter Sky," which he co-runs with a Wes Andersen whose identity is not precisely known. 

The brand claims to create pieces that "transcend traditional limitations in countless environments and numerous climates." Thanks to Nathan's devotion and skills, the minimalist clothing brand has grown. 

NATHAN IS A CANCER SURVIVOR 

As a married couple, Nathan and A.J. have had to weather storms together, and the most important seems to be the former's cancer battle. 

Nathan's battle with the deadly disease is perhaps the most difficult challenge the couple has had to face. Although the exact details about the ordeal are not known, Nathan and A.J. have shared that he is now cancer-free. 

Nathan celebrated the breakthrough with an Instagram post dated September 10, 2019. The post is a closeup picture of a scar on Nathan's neck, a by-product of his cancer battle.
