Warren Beatty and Annette Bening heading for divorce?

OHMYGOSSIP — Warren Beatty and Annette Bening are on the rocks. Friends of the Hollywood power couple — who haven’t been seen photographed together in public for at least six months — fear they could be on the fast track to a $108 million divorce.

Thension over the their transgender son Stephen’s lifestyle has finally reached the boiling point. Stephen, 21, was born a female and named “Kathlyn.”

He began his transformation into becoming a man in 2010 and now takes hormones to sound and look more masculine, a source told American tabloid the National Enquirer.

While Mom Annette, 55, has fully embraced his new identity, her 76-year-old husband has had a “very difficult time coming to terms with it,” the source continued.

“Warren doesn’t understand the whole transgender thing at all, and it’s driven a deep wedge in his marriage. Although Annette and Warren still love each other, pals believe that the next step could be divorce court.”

Warren was left furious when Stephen recently made a public service announcement, protesting a New York State Medicaid regulation that excludes transgender people from getting healthcare coverage.

In addition to becoming an outspoken advocate for the transgender community, the college student also revealed on Twitter that he has a boyfriend, blithely noting: “I’m trans and gay. Double the fun.”

“Warren’s an intensely private person and he’d rather that Stephen keep his sexuality more low-key,” explained the source.

“Stephen’s activism has deeply affected Annette and Warren’s marriage. They don’t communicate much and don’t seem to want to be in each other’s lives anymore. No one is cheating with anyone else – they’ve just drifted apart.”
