The couple met on the set of the 1993 movie Sommersby - an English language version of the French film The Return of Martin Guerre - in which 45-year-old Miss Foster starred with Richard Gere.

But it was during an acceptance speech at a Los Angeles film gala in December that the two-time Oscar winner first spoke about Miss Bernard, calling her: "My beautiful Cydney, who sticks with me through the rotten and the bliss."

The couple have two children - both of whom Foster gave birth to, and 54-year-old Bernard adopted.

For several years, the two women have worn matching Tiffany eternity rings on their wedding fingers and Miss Bernard was with the actress throughout both her labours.

A source told the American magazine National Enquirer: "Jodie breaking up with Cydney is shocking. She and Cydney have been together for so many years and have two children together, the potential fallout and legal wrangling from this split could be monumental."

Friends say Miss Foster has refused to employ household staff for fear that details of her home life would leak out.

Her mother, film producer Brandy Almond, and her father, retired air force colonel Lucius Foster, broke up before her birth and her mother later lived with another woman.

That role was to have devastating consequences years later when obsessed fan John Hinckley attempted to assassinate President Ronald Reagan in 1981 - he claimed he had planned the killing to impress her.

Miss Foster has remained terrified of stalkers ever since, according to her friends. Last night, the actress's publicist was unavailable for comment on the alleged break-up.
