Warren Beatty was trying to solidify his relationship with Stephen, his teenage daughter who became a man and was previously called Kathlyn, at a special family dinner in Hollywood on Saturday, according to the National Enquirer.

A source told the National Enquirer the special family meal at Italian restaurant il Covo was a way for Warren Beatty to publicly give his support to the 19-year-old, who decided she wanted to switch genders last year, but had been living as a man for at least two years previously.

The source said: “The dinner was an unofficial public display that he’s proud of his family, especially Stephen, for having the courage to be who he truly is.

“It wasn’t easy for Warren. But he learned a lot about the transgender community over the past year.”

As a result Warren Beatty, 74, is now bragging to friends about his “intelligent and courageous son Stephen”.

The source added: “Warren even made an emotional toast to Stephen during the dinner and said he was proud to have such a brave son.”

The person who was most pleased by the Bugsy actor’s new found understanding was his 54-year-old wife Annette Bening.

The source added: “Annette was simply glowing. She said the evening was the best Christmas present she’s ever received.”

Despite the fact it has taken some time for the Shampoo favorite to come to terms with his former daughter, who was named after his beloved mother, his feelings for him were never in doubt.

The source said: “Warren never stopped loving their child, but he had plenty of issues and fears to overcome.

“The bottom line is he missed his little girl. But he’s finally resigned himself to the fact that one day Stephen will probably have gender reassignment surgery and legally become a boy.

“Warren still slips up and calls Stephen <<her>> or by his birth name Kathlyn, but the bottom line is he’s totally onboard with his child’s new lifestyle.”

Stephen Beatty is one of four children the Oscar winning sex symbol has with Annette Bening.

Warren Beatty and Annette Bening have another two daughters, Isabel and Ella, and a son Ben.
