Arnold Schwarzenegger: His daughter congratulates her 75th birthday

Arnold Schwarzenegger celebrated his 75th birthday on Saturday (July 30). To congratulate her father, Katherine Schwarzenegger (32) shared several childhood photos on Instagram, showing her with the "Terminator" star. "Happy Birthday Dad!! We love you so much! You are the best and funniest grandpa and dad and we are all so lucky to have you in our lives!" the author captioned her photos.

A picture shows Katherine Schwarzenegger with her father on a ride – he makes her dog-ears. Another picture shows the two fooling around in a swimming pool. Another photo shows the actor and his two daughters Katherine and Christina Maria Aurelia (31).

However, the last photo in the series does not show the native Austrian with his daughter. The shot, taken from behind, is most likely a snap of Arnie and his grandchild, Lyla Maria Schwarzenegger Pratt (1).

Actor Chris Pratt (43), Katherine Schwarzenegger's husband, also congratulated his father-in-law with an Instagram post. The 'Guardians of the Galaxy' star shared a photo of himself smoking a cigar with Arnold Schwarzenegger.

He wrote: "Happy Birthday to the man, the myth, the legend. Love you Arnold Schwarzenegger."
