Ed Sheeran lines up possible side projects in 2013

Ed Sheeran says he could launch a new side project, after he's finished promoting his debut album +.

The singer's second album may not come out until 2014 after he said he wanted 18 months in between releases.

He'll spend a few months during 2013 supporting Taylor Swift in the US, but says he already has 24 songs written for a new album.
