Following Schwarzenegger's public admission of his infidelity earlier this week, an apparent family source told Us Weekly that 21-year-old Katherine, 19-year-old Christina, 17-year-old Patrick and 13-year-old Christopher are focused on helping Shriver through this troubling time.
"The kids are all banding together to support their mum right now and they're doing their best to stay out of the spotlight," the insider claimed.
Eldest daughter Katherine, who expressed family unity on her official Twitter page this week, is thought to be particularly concerned for her mother's state of mind.
The source went on to say that all four kids feel "really betrayed and embarrassed that [Schwarzenegger's affair is] out in the open", adding: "Not for their dad's sake but for Maria."
It was reported today that a close friend of Shriver has claimed that Schwarzenegger "completely betrayed" his wife by "concealing" a secret affair for more than ten years.
Schwarzenegger and Shriver announced their separation one week before the Austrian admitted to carrying on an extramarital relationship with a household employee believed to be Mildred Patricia Baena.
