MOST EXPLOSIVE WEEK EVER! COVER-UPS, SABOTAGE AND WALKOUTS!

STARS GO AWOL AS IT ALL GETS TO BE TOO MUCH

It's a mass exodus on The Block, with a TV insider revealing not one, but three Blockheads storm off set within days of each other during the most drama-filled week yet! Devoted mum Sarah-Jane is forced to flee the site and head home due to a family health emergency involving her and husband Tom's 1-year-old daughter, Cleo, spills an insider.

"It's a no-brainer for Sarah-Jane and Tom - family comes first," says an on-set spy of the couple, who were sent into a spin when their little one had to be taken to hospital with a worryingly high fever.

"I don't care if we don't get this bathroom done, my daughter needs me, I'm going home," says the reality star, who fearfully breaks down with worry as she ditches The Block for her baby.

"It was a tough couple of days for Sarah-Jane and Tom," says an insider. "Thankfully, all was good and Cleo is OK." Sarah-Jane, 30, isn't the only one downing tools though.
