Justin Lee Collins is to stand trial for allegedly harassing his former girlfriend.
The Friday Night Project host, who is 37, has denied putting ex-partner Anna Larke in "fear of violence" between January and July last year.
The comedian, of Kew, south west London, appeared at St Albans Crown Court for a plea and case management hearing.
Wearing a navy blue jacket and blue shirt, Collins spoke to confirm his name and to plead not guilty to a charge of harassment, causing fear of violence.
The case was adjourned for trial at St Albans Crown Court on September 24.
Collins was granted bail on condition that he does not contact Ms Larke or her relatives.
