Jonathan Ross was left red-faced when he tried to give his wife a nude surprise -- and ended up flashing a film director.
The presenter turned up to wife Jane Goldman's workplace stark naked, but ended up baring all to the unnamed director.
Ross, who ended his BBC shows in the summer, revealed all about the incident in a one-off Channel 4 chat show hosted by Jamie Oliver.
The controversial broadcaster -- who ran into trouble after leaving obscene messages for Andrew Sachs during a Radio 2 programme -- said he often tries to put screenwriter Goldman off her work.
He said: "For some reason a friend of mine bought me a white top hat for my 50th birthday.
"I went down to where my wife was working and just before I got there I took all my clothes off, put on the white top hat and walked in.
"I didn't know there was a world famous film director in there -- Jane shooed me out very quickly."
Goldman has worked on scripts for movies such as 'Stardust' and 'Kick-Ass' and on 'The Debt'.
The interview will be screened on 'Jamie's Christmas Lock-In' on Thursday at 10pm.
