Plan B is holding up filming of 'The Sweeney', in which he is set to play Detective Sergeant George Carter, because he is so in demand.

The 'She Said' singer-songwriter has been so busy with his music career that he admits his jam-packed schedule is preventing him from being able to focus on his acting scenes, and told the BBC:

"As soon as I've finished touring in America with Adele I'm going to finish my film, finish my next album and start work on The Sweeney in November. I'm kind of holding it up."

He won't be rushing back from his tour of the USA, though, as he confesses that he's a perfectionist and always wants to get projects done properly:

"It's so important that I get the things I need to get finished completed and to the right quality. I could rush it out and say it's finished but I can't stand doing that. If I'm going to be 100 per cent up there (on stage) my mind has to be on that."
