The 35-year-old model, who separated from the singer in 2009 after being together for around three and half years, said she took a lot of time to get over that phase, reported Contactmusic.
"The only issue I've had was when me and Pete split. That's the only time I've cared... It's taken ages (to get over it) because emotionally I was destroyed," Price said.
"Looking back, I don't know how I survived. I was slaughtered. Before that it was all a bit tongue-in-cheek and 'whatever'. It wasn't always nice, but when I was with Pete I was with his management (Claire Powell's Can Associates) as well and I thought they were my friends," she added.
