It's a sad day, HGTV fans. Flip or Flop stars Christina El Moussa and Tarek El Moussa revealed that their contractor and longtime friend Frank Miller passed away on Nov. 17, after losing his long battle with cancer.

"Good bye My dear friend Frank," Tarek wrote in an emotional letter to his lost pal on Instagram. "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've never met anyone like you nor will I ever. I just love you love you love you more than you know! I will NEVER forget you and I hope to one day be as strong as you. Now…don't slack!!!! I assume you are already working on remodeling heaven!!!!:):). Miss you buddy!!!❤️❤️❤️❤️❤️"

Christina was equally torn up, writing "Frank since the day I met you I had the utmost respect for you. 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❤️ #RIP."

Just two weeks before Frank's death, Tarek took to Instagram to beg fans for prayers after a variety of treatments failed to stop his throat cancer from spreading all over his body, and finally to his brain.

This is a long update but an important one. The treatments fighting multiple cancers caused his face and body to swell 10 times the size it should be.❤️❤️❤️ . Frank really needs our prayers now more than ever. He was in immunotherapy for the past 5 months and it was the only treatment that stopped his cancer from spreading. He did so much prior treatment from chemo to radiation to chemo and radiation at the same time and the cancer was so aggressive that it kept spreading. The immunotherapy was the final treatment that his oncologist could offer with his health and miraculously the cancer stopped spreading. That was up until 2 weeks ago he got another pet scan to see if the cancer was still at a halt and unfortunately that wasn’t the case. The cancer began spreading again and is working its way to his brain. At this time the doctors don’t have any other options so he reached out to the Lazarus foundation who has helped him previously about a new clinical trial they are offering throat cancer patience. Luckily, they have accepted Frank into this trial and is now waiting to begin treatment with them. Frank was supposed to begin the trial this week up until the incident that occurred on Monday Oct 23. Frank got such a bad infection in his lungs it which caused a severe pneumonia that his body went into shock and he was incoherent and fell off his bed causing him to fracture his head in 2 places. He was rushed to the hospital at UCI where he was in the cardiac care unit and put on antibiotics and is currently in stable condition. Frank will remain in the hospital a couple more days to fight off the pneumonia so he can be healthy enough to start the clinical trial that Lazarex foundtation has offered. Frank said that “Dying is not an option” and he sure means it. He is a fighter and so much of his strength comes from his family, friends and supporters. Please keep him in your thoughts and prayers.

Frank was a remote guest on The Doctors one month before passing away. At the time he said "every day is a good day, just some are a lot better than others." He also admitted that the love and support from friends and fans "kept him going." Everyone from the Flip or Flop family presented him with a touching video about how much they love him. Frank will definitely be missed.
