Prince William joked about getting drunk with Eugene Levy as he made a surprise cameo in a trailer for the new series of his travel show.

The Prince of Wales was seen on a walk with the Hollywood legend in a teaser clip for the third season of The Reluctant Traveler, which is due for release on September 19.

William, 43, appears at the end of the video, when he chats about getting drunk with the 78-year-old comedian, who is best known for his show Schitt's Creek.

It appears that the trailer has been shot in Windsor Great Park - with Eugene also seen walking around the grounds of Windsor Castle earlier in the clip.

Prince William jokingly asks Eugene: 'Was getting drunk with Prince William on your bucket list?'
