Kym Marsh had shocking rows with the rest of Hear'Say which drove her to depression, a report has claimed.
She did not get on with Myleene at all because of a personality clash, the News of the World reported.
It also says Kym, 25, reckons the rest of the band were jealous of her relationship with EastEnders star Jack Ryder.
Whispering behind her back
She apparently said none of the band made an effort to get on with him and were envious because he was more famous than they were.
Kym, who has left Hear'Say and wants to pursue a solo career, also attacked Noel for whispering behind her back and siding with Myleene against her, the paper claims.
