Joan Collins and Jackie Collins half-sister has been exposed - as a British Army Major.
Natasha Foster, 40, turned her back on a jet-setting life in the fast lane and chose to serve her country instead, and she's convinced her famous siblings have no idea she's such a heroine.
According to American tabloid Globe, Foster was stationed in Hong Kong and Germany and she was almost killed by a car bomb while serving in Northern Ireland.
And when civilian life failed to make its mark on her, Foster signed up for the reserves and headed to Iraq.
She says, "I don't think Joan has any concept of what I do."
