Keira Knightley has revealed that she couldn’t be a CIA agent like her onscreen lover in ‘Jack Ryan: Shadow Recruit’, because she is ”terrible” at keeping secrets. While the 28-year-old beauty plays the love interest of a CIA agent in the new flick, she insists she could never be a covert operative herself because she would end up spilling all the classified information. Speaking at the European premiere of ‘Jack Ryan’ in London’s Leicester Square, she told BANG Showbiz that she’s terrible at keeping secrets, and it would come straight out of her mouth, so she would be an awful CIA agent.
