Amy Winehouse’s husband Blake Fielder-Civil is reportedly hiding a forbidden mobile phone in his jail cell in Pentonville prison.

A source told the Sun that Blake is texted pay-as-you-go codes to keep the camera phone working and is using it to call and text Amy and “music industry associates”.

The source didn’t know how Blake had acquired the phone but said: “I don’t think Blake realises how much trouble he’s in if [prison officers] find it.”

Blake recently had his visiting rights restricted after failing a drugs test and will now only be able to see his wife of seven months through a glass screen. He is scheduled to stay in the jail on remand until at least the end of January, with his trial fixing court case set to take place next June.
