Comedian and television presenter Justin Lee Collins made his girlfriend recount every sexual experience she ever had for a notebook he kept as part of a campaign of domestic abuse, a court has heard.
The 38-year-old also made Anna Larke sleep facing him, the jury heard, rousing and criticising the video games public relations worker if he awoke and found she had turned away from him.
The performer assaulted and harassed his girlfriend during their nine-month relationship last year, prosecutor Peter Shaw told St Albans Crown Court.
The jury of nine women and three men heard that Collins, who came to fame with Channel 4's The Friday Night Project, made Ms Larke, 38, close her email, Facebook and Twitter accounts after reading her messages.
The comic, who also appeared in West End musical Rock Of Ages, made her throw away her DVD collection "on the basis she found some of the male actors in the movies to be attractive", it is alleged.
Ms Larke also told police that the comic "has a problem with people of colour", and the jury heard a recording of him accusing her of infidelities with men from ethnic minorities.
They met while Collins was still married. Ms Larke helped him move from Bristol to Kew, south-west London, in January last year before she moved in with him.
Collins "exhibited a desire to restrict" his girlfriend's activities during their relationship, controlling, verbally abusing and physically assaulting her, Mr Shaw said.
"Significantly, Mr Collins resorted to compiling a dossier in the form of a Pukka Pad notebook. The purpose of the notebook was to list every sexual experience with every one of Ms Larke's previous lovers or partners. He would ask her questions and then write it down," he said.
Collins, who denies harassing his ex-partner, sat in the dock wearing his trademark beard and long hair.
