Lindsay Lohan is reportedly set to convert to Judaism for her girlfriend Samantha Ronson. The 22-year-old singer - who is said to have been raised in a Catholic household - is considering altering her religious beliefs to bring her closer to DJ Sam, who she has been dating since late last year.

A source said: "Sam's family is Jewish. Lindsay has learned a lot about Judaism from Sam and admires its beliefs." However, friends of the 'Mean Girls' actress have doubts about her intention to fully convert to the religion and think she is just doing it for attention.

The source added to Life and Style Weekly magazine: "Two years ago it was Kabbalah. Last year it was Alcoholics Anonymous. She was into 'peace' for a while. Whatever is of the moment, that's Lindsay.

But the one thing it does show is her commitment to Sam. She could be any religion and Lindsay would be open to it." Meanwhile, 31-year-old Samantha has spoken for the first time about her relationship with Lindsay.

In an interview with Harper's Bazaar magazine, Samantha said: "Lindsay is great. But she's also 22 years old. I think people forget that. With the Internet the way it is, one second we're enemies, one second we're best friends, one second we're lovers, and then we're broken up. "

Even the airport security guy in Canada asked me, 'So is it true?' It's like, 'Oh, yeah, I'm telling you!' " Lindsay refused to comment on the relationship, adding in an email to the publication: "I love the Ronsons. They're close to my heart and I respect all the work they do. But Samantha and my relationship is a private matter."
