In more shock reality TV news, Joh Griggs has announced she has quit her role as host of House Rules.
Taking to Instagram, she wrote: "Hi @houseruleson7 fans. Thank you for your incredible, passionate support throughout Season 7, & congratulations to our Champions Pete and Courtney.
"I've got some news for you all. After a great deal of consideration, I recently sat down with the Network to ask to be allowed to step down as Host of House Rules. They have very graciously agreed for me to do that, which I'm incredibly appreciative of. As the show goes into preproduction for the next season, it's the perfect time to hand over the role to someone who will take the show into S8.
The TV personality went on to reflect on her time on the show, on which she has been front and centre since 2013.
"Reality TV production has been an eye opener, they are such enormous beasts with so many people involved, and I've had a great time over the last 7 years steering the ship, getting to work with many of my favourite camera crews as we criss-crossed the country... & having a blast playing Dress ups & experimenting with different looks.... with two of my best friends in Rosie Trindall (Stylist Extraordinaire) & Lisa Soames (Hair and Make up guru). It was a seriously fun part of working on the show," she wrote.
Joh also took the opportunity to thank her fellow on-screen colleagues as well as those who work behind the scenes.
"As was collaborating with two great writers in Grant Osborn & Robert Adams along with numerous audio operators as we recorded the voice overs. Sometimes we giggled so much, it was hard to get the words out!
"I've worked with fantastic judges in Joe Snell, Drew Heath, Jamie Durie & Laurence Llewellyn-Bowen... & the beautiful & talented Wendy Moore right from the start of the show. She & design mentor Carolyn Burns McCrave helped make every series so much fun. (Go the Girl (staying) Power!!) But the best part always for me, has been getting to know the teams. We've laughed & cried together; they all trusted me very quickly & made my job incredibly easy which I'm so thankful & grateful for."
Concluding the post, Joh said she was focusing on other work opportunities, including her hosting role on Better Homes and Gardens.
"My role as host of Better Homes and Gardens, which everyone knows I'm crazy about, keeps me very busy. Hopefully now though, with a different work load, I'll be in a better position to take up one or two of the great opportunities that come my way, especially with 7 Sport, which is such a passion for me," she penned.
Signing off, Joh wrote: "But thank you for being such a fun audience to interact with. Now I'm returning to my holiday with my darling husband."

The announcement comes just one day after rival network, Channel Ten announced longtime MasterChef Australia judges George Calombaris, Matt Preston and Gary Mehigan would not return after 11 seasons.
Network Ten chief executive officer Paul Anderson said in a statement: "Despite months of negotiation, 10 has not been able to reach a commercial agreement that was satisfactory to Matt, Gary and George.
"Across 11 sensational seasons, MasterChef Australia has established itself as one of the most popular and respected cooking television series around the world. For more than a decade, the iconic series has shaped and driven the Australian public's passion for food and cooking, delivered iconic television moments, and made the culinary dreams of everyday home cooks come true," he added.
"We would like to thank Gary, George and Matt for their contribution over the past 11 years."
Woah, looks like primetime TV just got a massive shake-up!
