The BBC presenter Fiona Bruce was harassed by a viewer who sent her flowers and cards which he signed "your kingfisher and loving husband", a court heard.
Australian-born Peter Oakey, 51, of Brentwood, Essex, sent more than 20 cards to the Antiques Roadshow presenter, Basildon Crown Court heard.
Prosecutors said Oakey, who admits breaching a restraining order imposed in December 2008 banning him from contacting Ms Bruce, had a history of "conduct of a similar nature". He had previously appeared in court after writing "offensive" messages to a number of businesses, Judge John Lodge was told. The presenter made a statement saying Oakey's behaviour left her "disturbed" and "distressed". The judge adjourned sentencing until 7 October.
