London, Nov 3 (ANI): It appears troubled Brit pop group Sugababes have yet to overcome their problems, with the release date of their new album, ‘Sweet 7′ being pushed further back.

The disc, which is a joint venture between Jay-Z’s Roc Nation and Island Records, was originally scheduled for release on November 23, but it has now been shifted to February next year, reports the Sun.

It is a big blow for the group, with Keisha Buchanan ousted and Amelle Berrabah recovering from a breakdown, and they already having pumped a lot of money into advertising the release date.

New member Jade Ewen has been working hard recording her lyrics on the disc and learning the back catalogue of songs but still needs a few more months before she can put in a perfect performance. (ANI)
