Actress needs time to convert to the star's Jewish faith
The couple have put the wedding on hold because the actress, 32, is yet to complete her conversion to the Jewish faith.
They were planning to tie the knot later this summer.
‘Sacha is a strict orthodox Jew and wants to do everything right to please his family,’ a source tells the Daily Mirror.
‘They have no plans to break-up. They’re totally in love.’
The pair are parents to Olive, 7 months.
Sacha, 37, was unavailable for comment.
