Janice Dickinson's Fiancé Accused of Sex with Patient

EXCLUSIVE

Janice Dickinson can no longer brag about dating a doctor, because the man she's set to marry just surrendered his license ... TMZ has learned.

Psychiatrist Robert Hugh Gerner allegedly engaged in a sexual relationship with a female patient from 2004 to 2011, and even lived with her during the last 3 years, according to docs filed in the case.

All that was before he started dating Janice, but the bigger problem is breaking the code of ethics. The California Medical Board filed a complaint against Gerner in 2015, and he waved the white flag in June of this year.

It isn't the first time Dickinson's fiancé has been through something like this. According to docs, he was suspended for 60 days in 1994 for sexual misconduct with another patient.

We reached out to Gerner's people, but so far no word back.
