The irrepressible television presenter has confirmed he's returning to poke around famous people's homes for a Christmas special in December, followed by a full series in ITV.
Keith said: "Keyhole series four! Nice t' be back having a nosey around the gaffs of famous folk.
"It's literally like doing a tour of England and stopping off at some lovely houses, oh and then we pop off to America, France and where else did we go? Or should I say where did we not go? Well loads of places, but we did also go to loads of places!
"We've got some ace houses this series and some great panels! Enjoy!"
This time around, Keith will be joined by an all new panel of celebrities including Eamonn Holmes, Caroline Flack, Kelly Brook, Emma Bunton and Judge Rinder.
Paddy McGuinness, Shayne Ward, Jonathan Ross, Jimmy Carr and Johnny Vegas will also be on hand to help discover the identity of the homes' mystery owners.
In each of the eight episodes, Keith will have a wander around houses belonging to three mystery celebrities. And he's getting a nice little vacation out of it as he'll be off to destinations including LA, Malibu, Palm Springs and the South of France.
