Saturday was Arnold Schwarzenegger's 75th birthday

Ahead of his birthday, Arnold Schwarzenegger celebrates the memory of his mother. 

The actor shared pictures of his mother, Aurelia Jadrny, on Twitter on Friday. 

Schwarzenegger turned 75 on Saturday. She died in 1998. 

The star of "Terminator" wrote on Facebook that her mother, Aurelia, would 

have turned 100 today. It is impossible for me to forget my mother, the best 

mother one could ever hope to have. It is impossible to describe how much  

she means to me, but I cannot claim to be self-made without her."
