Many have attributed Jon's shocking descent -- from attending high-profile events with the likes of Paris Hilton to being behind bars for innumerable counts of sex abuse -- to his erratic 'celebrity' lifestyle.
Jon boasted of an exclusive clientele including socialite Paris Hilton and American Idol judge Paula Abdul. He had also been a judge of the hit TV show America's next top model.
He cultivated his celeb image by making sure that an entourage followed him wherever he went.
A source close to the designer said that Jon led his 'life like a cult', with his associates clinging on to him, and that he was always accompanied by a photographer, his sister, who assisted him, and his publicist.
"He runs his life like a cult. He has four people following him around at all times, including a publicist, a photographer, and his assistant, who is his sister," The New York Post quoted the source, as saying.
The source added that the 33-year-old, who was arrested on March 13, was often seen with girls seemingly 18 years of age.
"He always had young girls around. They may have been over 18, but they didn't look it," the source added.
