What a card: Kevin Spacey was out jogging on Monday in Boston when he spotted a woman having her picture taken and decided to make a surprise cameo appearance.

"Apparently he jogged up, shouted 'PHOTOBOMB!' and then ran off laughing," says a friend of the woman's.

As has been noted by others, shouting "bomb" in Boston while running on a Monday when hats and bags are involved is an extremely risky move, but luckily for Spacey, he's above suspicion.
