Blatt has worked with Artful Dodger's Mark Hill

She said she realised the band could not stay together "as soon as the money started rolling in".

"We were great friends, we were good in band together, but we were not good at the business side," she said.

"We couldn't mix the friendship and the business, it was too hard."

She added that her new solo career is "terrifying".

Blatt was interviewed by Nemone on Radio 1

"[Shaznay Lewis] has been at my side for the last six to seven years of my life, and now she's just not there and it's really scary," she said.

Blatt is about to release her first solo single, Twentyfourseven, with Mark Hill from garage band Artful Dodger.

She said the first time she appeared solo on live TV, on CD:UK, was "awful".

Success

"I spent the morning wearing high-heeled boots, and when I heard the music at the start of the show my knees went so I had to put my trainers back on," she said.

Of the other former band members, Lewis is to star as the captain of an amateur football team in a new film and is believed to be working on new music with Robbie Williams' songwriting partner Guy Chambers.
