According to said source, Heidi reportedly brokered a deal with Amelle Berrabah to get the alleged “bully” out of the band.
“Keisha clashed with Amelle since she joined” said the source. "Heidi did not want to be in a position where a big bust-up might arise while they're promoting their material Stateside.
"So she persuaded management a less headstrong character would be better suited to the group."
But Heidi’s treachery hasn’t come cheap; the group have had to book round-the-clock studio time for new bandmember Jade to record her vocals on their new album, and Keisha is rumoured to have received a sizeable six figure pay-off as a result of the split.
