The future of X Factor judge Tulisa's debut solo album is reportedly up in the air after she split from boyfriend Fazer, who was producing the record.

As reported last week, Tulisa split from Fazer amidst reports she was unhappy with his growing friendship with Topshop heiress Chloe Green. However, the split has had disastrous effect on her album.

"Fazer was basically masterminding Tulisa's whole album," a source told the Daily Star.

 "He's still planning to be involved but nowhere near to the extent he was supposed to be. The first single is done, which should still be out in the spring, but the chances are the album will be delayed now to later in the year."

"They are both understandably finding it hard working together so closely after the break-up," the source added."

Tulisa revealed last week that her first solo single is ready to go.
