Celebrity blogger Perez Hilton has vowed to be more positive in his reporting these days but the jeweler who designed Angelina Jolie's engagement ring with Brad Pitt clearly does not think Hilton is succeeding at it.

Robert Procop is suing Hilton, whose real name is Mario Lavandeira, for reporting on his fashion site CocoPerez.com that the jeweler had been successfully sued by a previous customer for fraud.

The lawsuit, filed this week in Los Angeles, states: 'The statements that Plaintiff was 'guilty' of fraud in connection with his jewelry business and that a court had awarded a judgment against him for that fraud is libelous on its face. Those statements expose Plaintiff to hatred, contempt, ridicule and obloquy and they naturally have a tendency to injure Plaintiff in his occupation as a jeweler and jewelry designer.'

Procop is seeking $500,000 in general damages, plus special and punitive damages in a sum sufficient to punish and deter Hilton 'from engaging in such conduct in the future.'

According to TheWrap.com, Hilton's post came from a RadarOnline report that was taken down at the request of Procop's attorney. Hilton 'refused to retract the defamatory statements and take down the Article from his web site even after he was informed of their falsity,' the suit states.

Hilton has not commented on the suit but the post can no longer be found on CocoPerez.com.
