Well, Shania, Paris, and all the other celebs whether they be TV stars or not need prayers just like everyone else. The only reason we're shocked about their sins is because they're broadcast on TV and such. I've never really been a fan of Shania but as for Paris, I'm glad that something at least happened. She said something about acting immature and that this experience has taught her something. So I'm not going to beat down on her too hard or anything...
Besides, we shouldn't be judging people just because they commit sins. We all commit sins, and it's like what Jesus said when the elders and other officials were trying to stone a woman caught in the act of adultery: "Let the one among you who is without sin cast the first stone." And everyone knew that was not possible so they all left, leaving Jesus with the woman, the latter being forgiven of her sins by the former, because not even He condemned her. This gives all of us humans hope, doesn't it?
I'm not saying that I'm condoning anything either of the two does, but what I'm saying is "love the sinner, hate the sin". Maybe they just don't know any better because no one ever taught them morals as they were growing up. If a child is raised in a certain environment, maybe that's all they ever know unless they break out of it themselves. Anyways, I just say to pray for them.
EDIT: Now, if they're condoning sins in their music, you shouldn't be listening, but still...
RESPECT THE UNBORN AND CHOOSE LIFE...your mother did.
