Oy Vey! Is Lindsay Converting?

The couple that prays together, stays together. Since hooking up with girlfriend Samantha Ronson, Lindsay Lohan has been a staple at Jewish synagogues worldwide.

Yesterday in London, the two met up with Ronson's brother Mark for some afternoon worship time before indulging in some retail therapy. After picking up some intimates and stopping for a caffeine break, the two made another stop at the synagogue.

Though Catholic-bred Lohan has never made any official overtures to converting, a friend told RadarOnline.com that Ronson was definitely "an influence" on her.
