The beauty's famous spouse Arnold Schwarzenegger made headlines yesterday (17.05.11) when he admitted he fathered a child with a member of household staff ten years ago.
On Monday night (16.05.11) Maria - who is the former first lady of California - and her daughters dined with Oprah and her boyfriend Stedman Graham and best friend Gayle King at the city's RL restaurant.
A source told PEOPLE: "She was there with her daughters. The reservation was in Oprah's name."
Speaking of the news that her husband had fathered a love child, Maria requested that the media respect her privacy during the hard time.
In a statement she said: "This is a painful and heartbreaking time. As a mother, my concern is for the children. 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."
