Beware the Beliebers. Mariah Yeater found herself bombarded with death threats on Twitter after Star magazine reported that she had filed a paternity suit against Justin Bieber. “Dear Mariah Yeater, Roses are red, violets are blue, stay away from Bieber or Beliebers will kill you,” wrote one person. Yeater claims in her lawsuit that she had sex with Bieber backstage at one of his shows last year. Bieber denies the allegations. Yeater shouldn’t be surprised at the violent reaction of the Bieber fans. Last year Kim Kardashian got death threats after she met Bieber at the White House correspondent’s dinner. Selena Gomez, the singer’s current girlfriend, has also received threats.
