LOS ANGELES -- "The Janice Dickinson Modeling Agency" ended its third season in Miami with Dickinson dissolving her relationship with business partner Peter Hamm.

Come August, the self-proclaimed "first supermodel" will be back in Hollywood ready to shake things up when the fourth season of her reality show premieres on Oxygen.

Working with a new business partner, Dickinson will focus on moving her modeling agency from dealing with commercial to high fashion projects. She will also toy with starting a plus-sized model division, something that anyone who remembers her judging stint on "America's Next Top Model" will find hard to believe.

Dickinson will also take a hearing-impaired model under her wing. And, deciding that she needs to keep a closer eye on her assets, she will move herself and several of the agency's models into a Hollywood Hills mansion. While the models will more than likely have to room together, Dickinson will reside in a luxury master suite decorated by Madonna's brother, Christopher Ciccone.

The fourth season of "The Janice Dickinson Modeling Agency" premieres Tuesday, Aug. 26 at 10 p.m. ET on Oxygen.
