Evidence that Justin Lee Collins harassed his ex-girlfriend is to be heard in court tomorrow.
His trial opened yesterday, with the jury being sworn in, but the prosecution will not open its case until tomorrow.
Collins, 38, denies causing fear of violence to Anna Larke between January and July 2011.
The former host of Channel 4's Friday Night Project is currently appearing in the West End musical Rock of Ages.
St Albans Crown Court granted him bail on condition that he does not contact Ms Larke or her family.
