From the official H & Claire website:

Pop’s newly formed duo have just arrived back from song writing in Sweden with Jorgen Eloffsen.

They had a fabulous time and they’ve come up with some great new material which you will be hearing soon, and that’s a promise.

On the same day this was posted too:

H & Claire jetted off to Miami on Wednesday to film the video for their first single DJ which is to be released on 6 May.

They’re both having some great clothes specially made and, in what is now becoming tradition, they’re going to be decked out in diamonds again! It will be on the Box and MTV for the easter hols.
