The four (legitimate) children of Arnold Schwarzenegger are rallying around their mother, Maria Shriver, amid the love child scandal that exploded this week.
Three days after Arnold admitted he had a love a child with former household staffer Mildred "Patty" Baena, Maria is understandably reeling from the news.
The couple's four children - Katherine, 21, and Christina, 19, Patrick, 17, and Christopher, 13 - are struggling as well, but are rallying around their mom.

"The kids are all banding together to support their mom right now and they're doing their best to stay out of the spotlight," a family source tells Us Weekly.
The fact that Arnold kept the secret for 14 years, and that Baena is close to the family and was obsessed with Maria Shriver, make this harder to bear.
The former California governor's wife of 25 years struggles to maintain a brave face, her kids seek comfort in oldest sibling Katherine, who frequently acted as a "second parent" while Schwarzenegger was on the campaign trail.
"Katherine is really upset about this and how her mom is right now," the source adds."It's tense because the kids need a sounding board just as much as Maria does but it's difficult to go to their mom for questions. Everyone feels really betrayed and embarrassed that it's out in the open. Not for their dad's sake but for Maria."
Older brother Patrick admitted on Tuesday that he was suffering from his family drama. "Some days you feel like sh--, some days you want to quit and just be normal for a bit, yet I love my family till death do us part," he Tweeted.
"You have no idea how humiliating this is for her," one Shriver pal said when news broke of Schwarzenegger's fifth child, a boy who may have been born within weeks of Christopher, the couple's youngest child.
"[Maria] spent a lot of time ... defending Arnold's character. She had no idea."
