Tulisa's book deal shelved indefinitely

Former 'X Factor' judge Tulisa's plans to release her "gripping and powerful" 5 million-pound book 'Sky', which was due to release on September 26, have been delayed until further notice, according to reports.

Her spokesman explained that when Tulisa signed a book deal with Headline there were provisional plans made to release a debut novel in autumn 2013, the Daily Star reported.

The rep, however, added that a decision was made earlier in 2013 to continue work on the novel, with the view to releasing the book at a later date.

Also, speculations are rife that the troubled former 'N-Dubz' singer was on the brink of losing her 1 million-pound deal with fashion brand Bank, who are "reviewing their options".
