Hollywood star, Arnold Schwarzenegger goes on a bike ride with son David Baena

ARNOLD Schwarzenegger covered up with a face mask during a bike ride with his son David Baena on Friday in Santa Monica, California.

The 22-year-old opted to go on the outing with no protective gear as his dad, 72, wore a mask that read “we’ll be back” - a reference to his iconic Terminator movie line.
