Katie Price was ''emotionally destroyed'' when she split from Peter Andre.

The 35-year-old star has admitted she struggled to rebuild her life after her three-and-a-half marriage to the 'Mysterious Girl' singer collapsed in May 2009 and describes it as her worst break-up.

In an interview with the new issue of Now magazine, she said: ''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.

''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.''

Katie - who has two children, son Junior, eight, and six-year-old daughter Princess Tiaamii, with Peter, who also acts as stepfather to her child Harvey, 11, from a previous relationship - was ''really disappointed'' when things didn't work out with the reality TV star.

The brunette beauty - who met Peter, 40, when they appeared together on 'I'm A Celebrity... Get Me Out of Here!' - said: ''He's not the man I fell in love with. He used to think with his heart.''

Katie is confident her marriage to third husband Kieran Hayler - with whom she has a baby son Jett Riviera - will last because it isn't career focused like her romance with Peter.

The stunning star - who was also briefly married to Alex Reid - explained: ''Our jobs are separate. We (me and Kieran) go home and we're like a normal married couple, everything isn't documented.

''I think I'm more down to earth than people realise ... I'm vulnerable, gullible and I fall in love easily.''
