Farrell converting to Judaism?

Colin Farrell is reportedly abandoning his Catholic faith to convert to Judaism for new girlfriend Emma Forrest.

The actor, 32, has been dating British novelist Forrest since June, but the romance appears to be turning serious.

The couple attended a West Hollywood party for Heeb magazine at MBar earlier this month, where Farrell was seen wearing a chain with a Star of David pendant around his neck, according to the New York Post's Page Six.

A source adds that Forrest was seen doing "a striptease burlesque act to traditional Jewish music".
