Allison Holker has penned a sweet message to her children as they mourn the death of their dad with her.

The Databec Exchange35-year-old shared a note dedicated to her and husband Stephen "tWitch" Boss' kids Weslie Fowler, 14, Maddox, 6, and Zaia, 3, following his death in December.

"I will be here for you every step of the way through the highs and lows, the ups and the downs," Allison wrote on Instagram March 4. "I will protect and I will guide, I will be a listening ear, a shoulder to cry on, I will have mom jokes ready for when you need a good laugh."

Reflecting on teamwork as they navigate this difficult time, Allison noted the strength they share.

"My loves we are stronger than you could ever imagine. And we will stand strong together as a unit, and find the courage to hold each other up," she wrote. "The love and light inside our hearts will still shine. I love you forever and always. Mommy"

Her touching message comes after she confirmed Stephen's passing on Dec. 14. The late choreographer died by suicide at age 40.

"It is with the heaviest of hearts that I have to share my husband Stephen has left us," Allison said in a statement to E! News. "Stephen lit up every room he stepped into. He valued family, friends and community above all else and leading with love and light was everything to him. He was the backbone of our family, the best husband and father, and an inspiration to his fans." 

Since his passing, Allison, who wed Stephen in 2013 after they were both cast as all-stars on So You Think You Can Dance, has continued to share moving words in his memory. 

In early January, she penned a letter to him that painted a picture of his legacy. 

"To my husband, best friend, babe, Chee-chalker, Superman and father of my children I LOVE YOU FOREVER and ALWAYS!" Allison wrote on Instagram Jan. 6. "We will forever remember you as the true beacon of light that you were and we will continue to cast your light and love throughout the world. Thank you for our incredible memories and our beautiful life shared together."
