When Is A Cohen Not Jewish?

Until he converts if his mother isn't Jewish.  Here:

Peaches Geldof has become a mother for the first time.


She and fiancé Thomas Cohen welcomed a baby boy to the world - who they have called Astala - which they announced on their Twitter pages today.

It is unclear exactly when their little bundle of joy was born, but this afternoon, Peaches, 23, took to her page and declared: 'yes, it's true - I'M A MUMMY!'

UPDATE

And the baby boy's name is

Astala Dylan Willow Cohen-Geldof

Explanation:

'I wanted a Jewish name because my fiance is a Jew and the name is the male version of Esther.'

Astala? Estelle? What could be masculine there?

Esther's Hebrew name was Hadassah. Esther 2:7:

And he brought up Hadassah, that is, Esther, his uncle's daughter; for she had neither father nor mother, and the maiden was of beautiful form and fair to look on; and when her father and mother were dead, Mordecai took her for his own daughter.

And Hadassah means myrtle in Hebrew.

At least Peaches wears a Jewish star pendant.
