Both Tarek El Moussa and Christina El Moussa have taken to social media in mourning of a loved one.
The same loved one, it turns out.
On Friday, Frank Miller lost his battle with laryngeal cancer, passing away peacefully at an Orange County hospital in California.
The long-time contractor had worked closely with Tarek and Christina for years on Flip or Flop, the home renovation series that has been such a huge hit for HGTV.
In tribute to their late friend, the former couple shared memories of Frank and bid him farewell over the weekend.
“Good bye My dear friend Frank,” Tarek wrote, adding:
“I have always looked up to you and have respected you as a brother. You have touched not only myself and my family but thousands and thousands around the world.
"You have impacted so many lives with the fight inside your heart and soul…
"I will NEVER forget you and I hope to one day be as strong as you."
“Now…don’t slack!” Tarek concluded. “I assume you are already working on remodeling heaven! Miss you buddy.”
Christina also sent a few thoughts Miller's way.
“Frank since the day I met you I had the utmost respect for you,” she wrote.
Continued the popular HGTV personality:
“Hardworking and REAL. Always a pleasure to be around and always made me laugh. You fought your hardest!! You are so admired and respected by all who know you.
"God has a special place for you in Heaven. Love you and miss you.”
Tarek and Christina split up about a year ago.
They recently acknowledged their divorce and how far they've come in separate social media posts.
In May, the co-stars went public went the tale of Frank’s cancer diagnosis.
A GoFundMe account was sent up by Miller's co-worker, Alison Diaz, that ended up raising over $31,000 to help Frank cover his medical treatments.
“As some of you know… he’s been fighting multiple cancers for many years, even while filming our show, and he’s still putting up the fight of his life,” Tarek wrote on Instagram at the time.
“The doctors told him a year ago he would not make it past 6 months, he’s proving them wrong, this man is a beast.”
Tarek, of course, has overcome two different cancer diagnoses himself.
The GoFundMe remains active, it should be noted.
If you’d like to make a donation, please go ahead and do so.
May Frank Miller rest in peace.
