DiCaprio to become Jewish for girlfriend?

It has been reported that Leonardo DiCaprio is considering converting to Judaism for Israeli girlfriend Bar Refaeli.

It is believed DiCaprio, born Catholic, has been looking into the process of conversion in what is believed to be an indication that the couple are now considering marriage.

"Leo's sudden intense interest in Israel, its culture and religion is the clearest sign yet that he intends to marry Bar," a source told the Daily Mail. "Now he is looking into converting for her."

The couple, who have had an on-off relationship since 2005, have recently become the subject of several reports speculating that they have become engaged.
