Theres a lot. Its probably best to check it yourself as i only have second hand knowledge, but I know shes faced allegations of sexual misconduct multiple times, theres the stuff with eminem, theres the claim she stole “all i want for christmas” but i believe that was either dismissed or settled, its just a bunch of stuff. She doesnt seem like a genuinely shitty perosn, but from the sheer number of controversies shes not someone i would want to personally associate with or look up to.
