As Natalie Barr and Samantha Armytage's feud reaches fever pitch, David Koch is getting ready to step in to help his Sunrise co-star.
"Kochie is fed up with his former co-host's carry-on," a source tells Woman's Day.
"His support is 100 per cent behind Nat and he's ready to tell Sam to back off."
The industry source adds that crisis meetings were held at Seven following Sam's comments on The Kyle & Jackie O Show, with Kochie, 65, standing firmly by Nat's side.
"Kochie has been Nat's shoulder to cry on," the source adds.
"She's like family to him and he would be so cross with Sam. Her comments have left him shaking his head."
Sam, 44, sent tongues wagging last week when she tweeted that Nat, 53, should just "get on" with her job.
"Look.. I'm out. Nat's wanted the job forever.. & she's finally got it. She just needs to get on & enjoy it – and forget about me.. (even though I'm unforgettable)," she wrote.
