An Israeli nationalist group has urged Bar Refaeli to ditch boyfriend Leonardo DiCaprio - so she can settle down with a Jewish husband.

The supermodel, who has been dating the "Titanic" star on and off since 2005, was forced to deny rumors she was engaged to DiCaprio earlier this month after she was spotted wearing a ring on her wedding finger. She told reporters the couple had no plans to marry - but her comments failed to stop an Israeli politician from warning her to stay away from the actor.

Baruch Marzel's letter, sent on behalf of the Lehava organization, 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 adds 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."
