Lindsay's New Guardian Angel: John Travolta?

Just what Lindsay Lohan needs: a new religion! John Travolta has decided to take the troubled starlet under his wing and introduce her to Scientology, Showbiz Spy reports. Travolta and Lohan are both starring in an upcoming movie about the Gotti family, but LiLo only snagged her spot because Travolta promised to "keep her on the straight and narrow ... now and forever," in part by introducing her to his religion, a source says.

How does La Lohan feel about it? "She’s assured him she’ll still attend the series of induction classes that will make her a Scientologist," says the source. Click for more on the movie. (More Lindsay Lohan stories.)
