Arnold Schwarzenegger was joined by his girlfriend Heather Milligan and his son Christopher at the Kitz Race Party in Kitzbuehel, Austria on Friday.

The 76-year-old actor looked dapper in a sharp suit as he posed alongside his longtime partner, 48, and his 26-year-old son — whom he shares with ex-wife Maria Shriver.

He donned a deep navy blazer over a powder blue button-down and sported a pair of denim jeans. 

The former governor of California — who bundled up as he watched the competition at the FIS Alpine Ski World Cup on Sunday — completed his look with a pair of patent leather dress shoes.
