Richard Madeley has reported to the police two "peeping Toms''.
It's alleged they were flying a drone over his garden in Cornwall to spy on him.
The former This Morning host tweeted that he gave chase to the "creeps'', finding the suspected owners in a nearby white van, before contacting the police.
He posted: "So who are the two peeping toms who just flew a drone over my garden near Looe.
"Chased them down to a white van ... Drove off when challenged.''
Madeley gave the licence plate number of the two alleged perpetrators out on Twitter in a hope for information.
Famous couple Madeley and his wife Judy Finnigan have owned a property in Talland Bay, near Polperro, since 1998, according to an interview with the Plymouth Herald.
Drones with attached cameras have long sparked privacy fears among celebrities, including Kanye West, who has accused paparazzi of "stalking'' his daughter with the gadget.
