Heather McComb will remember James Van Der Beek as being "innocent, kind and pure of heart"

Heather, 48 - who married James in 2003 before separating in 2009 - wrote on Instagram: "I am heartbroken over the loss of beloved James. I am especially heartbroken for his incredible wife Kimberly, his beautiful children and his amazing family, Jim, Jared, Juliana and all of his family and friends who I know he loved deeply."

Heather subsequently described James as "a beautiful soul".

She reflected: "This is how I will always see James innocent, kind and pure of heart. What a journey we shared over the years. I sit here in immense gratitude for the special connection, friendship and love that James and I shared that has endured through decades. I will treasure the last loving words we exchanged.

"James was a beautiful soul filled with so much light, love, talent, humor, depth, sensitivity, knowledge and a deep love of God that shined through him.

"He shined so bright yet was so humble and human. Always searching, always growing, always going deeper, always chasing things outside his comfort zone.

"I know that James loved being a father so much and oh how he loved Kimberly with his everything. True soulmates. How she showed up for him with such grace is so beautiful and something I will forever admire. James was a blessing to all that knew him and because of his boldness to share his journey with the world so bravely is now a blessing to all. (sic)"

Kimberly, James' second wife, announced the actor's passing via a social media post.

There is much to share regarding his wishes, love for humanity and the sacredness of time. Those days will come. For now we ask for peaceful privacy as we grieve our loving husband, father, son, brother, and friend."
