Gregor Uwe-Steeb (né Gregory Lipstanski) is the chairman and founder of the Ciao! fashion company and married to the president Ciaobella Masterson. As he treats his employees disrespectfully and even steals designs from vice president Emily Bloom, he is not a very well-liked boss.
Gregor is having an affair with affiliated model Sigrid and wants to get out of his marriage, but he does not want to lose half his company to Ciaobella as a result of their nearing 10-year anniversary. He therefore poisons her green super food powder with arsenic. When Ciaobella finds out about the affair, however, she electrocutes him by tampering with the mic stand at a presentation. It seems Gregor's plan has failed miserably, but Ciaobella's bulimia meant that the poison simply needed somewhat longer to take effect, and she dies at his funeral. Later on it seems that Gregor will be responsible for a double homicide when Emily also uses the powder, but she manages to survive after having her stomach pumped.
- Chief Vick refers to Gregor as a "homegrown celebrity", so it would seem he was born and raised in Santa Barbara.
- Gregor married Ciaobella on Abaco, a small island in the Bahamas. Since this was a private ceremony, however, most people (including Shawn and Gus initially) were under the impression that the two only got married two years later and were approaching their 8th anniversary instead of their 10th.
