Television presenter Angus Deayton has obtained a High Court order stopping a newspaper publishing more details about his private life.
The injunction against the Mail on Sunday was issued after a three-hour hearing on Saturday.
A spokesman for the paper said the case raised important issues of public interest and they would be seeking a full hearing to overturn the decision.
Last month, in an interview with the News of the World, prostitute Caroline Martin claimed she had a "two-night affair" with the star.

She said she did not realise Deayton had a long-term partner and claimed they had swapped telephone numbers before meeting up at a hotel in Manchester and then again in London.
She described their encounter in detail, saying Deayton used cocaine in front of her.
Following the revelations, Deayton and his partner Lise Meyer flew off to Italy to escape the publicity.
But he returned to face ridicule on his satirical show Have I Got News For You.
