The 35-year-old model, who separated from the singer in 2009 after being together for around three and half years, has accused the pop star of making his career by demeaning her image, reported Daily Mirror.
"It felt to me as if he was building up his own career and image by trashing mine," Price says in her memoir.
The model revealed that the 'Mysterious Girl' singer ended their relationship over the phone.
"I thought we had a secure, happy family, something which I have always wanted. But that happy family was destroyed when Pete walked out - telling me it was over in a phone call," she said.
