A Cairo family court on Thursday ruled in favour of Egyptian actress Zeina who has sought legal action for over a year in a highly-publicised case to prove her twin boys are the sons of celebrated actor Ahmed Ezz.

The case was thrust into the limelight after the 38-year-old actress returned from the United States to Egypt in January 2014 after giving birth to twin boys Ezzeddine and Zineddine, which she claimed at the time to be the sons of the Egyptian actor.

Her lawyer said the pair wedded in June 2012 through a customary marriage, which in Egypt requires only two witnesses without the need for official documentation.

Ezz, 43, has consistently denied the marriage took place, and in turn refused to acknowledge being the father of the US-born boys. He repeatedly declined to undergo DNA tests required by the court.

In the Thursday hearing of the case that began in May 2014, the judge said the 20-month-old twins were proven to be the sons of Ezz. The court decision is still appealable.

"Today justice has been fulfilled to shut liars up," Tarek Gamil, Zeina's lawyer, said.

He added they were to issue Egyptian birth certificates for the boys.

The case is not the first to embarrass Ezz before his fans.

Late in 2014, local media published a copy of an alleged marriage contract between Ezz and leading Egyptian songstress Angham, dating back to 2011.

Ezz acknowledged in a statement shortly after that the marriage was kept a secret from the public due to family problems the singer was facing at the time.

Angham said she had the right to keep her private life away from public eyes, saying her family and friends were informed of the marriage, which reportedly lasted for a few months.
