Brit pop trio the Sugababes have been forced to push back the release of their latest album Sweet 7 to give new member Jade Ewen more time to learn all the new songs.

The Eurovision star was drafted in to replace founding member Keisha Buchanan in September after her bandmates Heidi Range and Amelle Berrabah decided they wanted to carry on the band without her.

The line-up change happened just two months before the band were set to release its seventh studio album - the trio's first record since signing to Jay-Z's Roc Nation label.

The release date was initially postponed from 9 November until 23 November, but fans will now have to wait until February to get their hands on the new album.
