Bar Refaeli has been urged by an Israeli nationalist group to ditch her boyfriend Leonardo DiCaprio in favour of a Jewish husband.

The supermodel's affair with the actor has been hitting headlines since the couple began dating in 2005, including speculation leading to their marriage.

An Israeli politician has now penned a letter, sent on behalf of the Lehava organisation, calling for the star to "come to her senses" and not dump her Jewish descent, the Daily Star reported.

Baruch Marzel's letter read: "It is not by chance that you were born Jewish. Your grandmother and her grandmother did not dream that one of their descendants would one day remove the family's future generations from the Jewish people. Assimilation has forever been one of the enemies of the Jewish people."

Marzel added that he "has nothing against Mr DiCaprio, who I have no doubt is a talented actor," before concluding: "Come to your senses, look forward and back too - and not only the present.

Don't marry Leonardo DiCaprio, don't harm the future generations." (ANI)
