Arnold Schwarzenegger's son Patrick, 17, is the first of the former California governor's children to break their silence in the wake of news regarding Arnold's infidelity. On Tuesday, Patrick tweeted, "Some days you feel like s---, some days you want to quit and just be normal for a bit, yet I love my family till death do us apart. #family."
Hours later, Patrick's older sister, Katherine, also shared her thoughts on Twitter.
"This is definitely not easy but I appreciate your love and support as i begin to heal and move forward in life," the 21-year-old tweeted. "I will always love my family!"
Patrick's Twittering first made the news last week after the separation was announced but before it was announced that his father has fathered a child with another woman. At that time, Patrick tweeted: “Appreciate all your messages. Small speed bump I'n life, luckily we own hummers, we will cruise right over it. All will be okay. #peace."
Arnold Schwarzenegger and Shriver have two children in addition to Patrick and Katherine: Christina, 19, and Christopher, 13.
Shriver earlier Tuesday issued a statement asking for "respect and privacy as my children and I try to rebuild our lives and heal."
