Kids

Baena kept the 13-year-old boy in the dark, says the New York Post, and neighbors say he even referred to Baena's current boyfriend as dad.

The paper says Baena's secrecy over paternity ran so deep, her own sister didn't even know until this week. That's strange, because some of Baena's friend who have spoken with TMZ tell us they've know for a while.

We're told the Christmas photo was taken inside Arnold's house around the year 2000.

People who live next door to Patty and her son tell us, the boy "is the type of kid you just want to be around. He is so sweet, funny, and handsome."

But that's not it -- we're also told he is extremely well-mannered and smart, loves sports, and is even involved in door-to-door fund-raising for local charities.

And get this ... the two kids were born less than a WEEK APART -- Maria's son Christopher was born on September 27, 1997 ... and Mildred's love child was born on October 2, 1997.

Sources say Maria was distraught after learning Arnold pulled a John Edwards. The baby mama worked for the family for two decades, retired and received a severance package, according to the L.A. Times.

The baby was born more than a decade ago, but until recently Maria thought the father was the woman's husband at the time.

Schwarzenegger told The Times, "After leaving the governor's office I told my wife about this event, which occurred over a decade ago. I understand and deserve the feelings of anger and disappointment among my friends and family. There are no excuses and I take full responsibility for the hurt I have caused. I apologized to Maria, my children and my family. I am truly sorry."

TMZ heard about the baby 5 days ago, but everyone in the Schwarzenegger camp was denying it. But sources told us Maria was "completely distraught" yet determined to move on with her life. She has not pulled the trigger to end her marriage on the legal side, but she has been working with a very powerful financial adviser who has been helping her position herself for a divorce.

We believe -- though have not confirmed -- there is a prenup, but the couple has been together so long the effectiveness of it is problematic.

UPDATE: Maria released a statement saying, "This is a painful and heartbreaking time. As a mother, my concern is for the children."

She continued, "I ask for compassion, respect and privacy as my children and I try to rebuild our lives and heal. I will have no further comment."

Child Protective Services in San Francisco launched an investigation last week after Kerry Campbell went on "Good Morning America" and told the world she gave her daughter Britney the anti-wrinkle injections herself ... to help her compete in beauty pageants.

According to ABC News, Britney has been removed from the home by CPS and taken into their custody while an investigation is conducted.

Sources connected to the most powerful man on the planet -- Justin Bieber -- tell us the singer was contacted by the White House on the SAME DAY Barack met with a 14-year-old Bieber fan whose father was killed in the 9/11 attacks.

Obama famously told the girl he "knows Justin" and could arrange for her to meet him -- but certain media outlets called BS on the promise and predicted Barack would never be able to deliver.

However, sources extremely plugged in to the situation tell us Bieber was super-excited about getting the call -- and told the White House he will DEFINITELY meet the girl when he returns to the U.S. and can get back to the East Coast.

So far, no date has been set.

It all started with a tweet from the fan's best friend who was trying to raise awareness about the girl's dire situation -- one of her kidneys was failing ... fast.

Donnie retweeted the link to his 183,000 followers, asking for help ... prompting a barrage of phone calls to Vanderbilt University Medical Center where the girl -- named Bobbette Miller -- was being treated.

According to the Boston Herald, the calls yielded SIX matches -- and Bobbette is now scheduled for a transplant in June.

The publicist wouldn't get into specifics, but insists little Luke is expected to be back at home with Gary and Gary's fiancee Steffanie Sampson by the end of the week.

According to Israeli news reports, Prime Minister Benjamin Netanyahu 86'd a scheduled meeting with the Biebs, after he reportedly refused to meet with kids who survived a recent rocket attack in Gaza.

Bieber's rep is not denying Justin wouldn't meet the kids, but says it's more of a scheduling thing: "Despite some logistical challenges, Justin is enjoying his first trip to Israel."

Roseanne and her ex, Ben Thomas, are in the middle of a trial to determine if Roseanne has to foot the bill for Ben's trips to Hawaii to visit their son, Buck. Roseanne lives in Hawaii and Buck attends school there.

During the trial today in L.A.County Superior Court ... Roseanne's legal team said they are in the process of filing for "sole legal and physical custody" of Buck.

Her attorneys expect to complete the process once the judge rules in the current trial.

Outside court, we asked how it went -- and Roseanne simply put her hands together to pray.

15-year-old Naijiel and 18-year-old Lil Nate revealed their game plan in L.A. yesterday ... and gave us a sample of the goods to boot.

The 4-year-old rocked a wife beater as he made his move on a pretty young thing at an L.A. park.
