Paris reportedly thinks Justin is a bad role model and is upset that he doesn't speak out against teenage girls cutting themselves, according to TMZ.
Paris resents that — after Justin's female fans recently started tweeting about cutting themselves to show their love for Justin — Justin did not say anything to discourage them or talk them out of it.
Paris — who is Michael Jackson's 15-year-old daughter — herself made headlines earlier this month when she took 20 Motrin and then cut herself with a knife in an apparent suicide attempt.
She also is said to dislike that photos were taken of Justin smoking weed in a hotel room in January, as she thinks Justin needs to be a better role model.
Plus, Paris lives in Justin's gated community in Calabasas and thinks that the way he behaves in the neighborhood is a "disgrace," sources say. This has led her to "hate" Justin, add the sources.
Is Paris a fan of Justin's? We're guessing the answer is: Baby, baby, baby, no.
