Coronation Street star, Jack P Shepherd, has caused a stir by taking of a photo (pretending?) to relieve himself on the sign for rival soap, Emmerdale.

Jack, who plays David Platt on the show, posted the photo to his Twitter account after a night out but deleted it within seconds.

An insider told The Sun that “Jack had a few drinks like the rest of the Corrie cast, but as the night went on he got a bit boisterous.” Yeah, no kidding!

The source revealed that the 27-year-old soap star has been in trouble before over inappropriate behaviour and that ITV bosses have warned their actors against this kind of publicity.

“Jack knew this could get him in trouble. There’s big rivalry between the soaps but the ITV bosses don’t want any headaches over rows.”

While Jack did delete the picture, he clearly isn’t feeling too shook up about the thought of possibly getting in trouble as he tweeted, “Now where’s that @bbceastenders set,” after the incident.
