InstagramHappy birthday, Katherine Schwarzenegger!
The daughter of Arnold Schwarzenegger and Maria Shriver turned 26 on Sunday and celebrated her birthday over the weekend with her family. Katherine's brother Patrick Schwarzenegger, 22, posted on his Instagram page an adorable photo of himself with Katherine, their parents and siblings Christina Schwarzenegger, 24, and Christopher Schwarzenegger, 18, standing around a birthday cake.
"Happy birthday sisssstaaah @katherineschwarzenegger," Patrick wrote on Sunday.
Katherine shared on her Instagram page a photo of herself at a joint birthday party with friends.
Happy 26th birthday Katherine," her mother said on her Instagram page, alongside a throwback head shot of Katherine. "You are beautiful inside & out I love you to the moon and back @katherineschwarzengger."
She also posted a pic of the two as well as what appeared to be one of Katherine's childhood school photos.
Arnold also shared a heartwarming birthday tribute pic.
"Happy birthday to my smart, independent, beautiful, strong, talented daughter," he wrote, alongside a throwback photo showing himself going horseback riding with Katherine when she was a little girl and making bunny ears behind her head.
"I love you, @kschwarzenegger," he said.
Arnold and Shriver broke up in 2011 after 25 years of marriage, after the Terminator actor and former California governor admitted he secretly fathered a son with an employee. He and Shriver were last photographed together in public in July, when they celebrated his 68th birthday.
