Kelly Brook was a "secret psycho" and broke into her boyfriend's phone to see if he was a cheat when they first met.

She confessed: "I'm a secret psycho. I like to be ahead of the game. So when I met my boyfriend, I got the password to his phone early.

"But all his messages were in French. So I screen-shotted them, sent them to my cousin who speaks fluent French and she translated -- and I realised he was a nice guy."

And Kelly admitted her past experiences influenced her behaviour.

She added: "I targeted him. In my twenties I was targeted, in my thirties I have to target."

Meanwhile, the brunette beauty has never been married but admitted the couple are happy and she wouldn't rule out walking down the aisle with the hunk in the future.

She told The Sun newspaper: "We've been together for over a year, we're not getting married yet, but maybe one day."

However, Kelly also confessed she loves sex and doesn't like to settle with one man for too long.

Kelly previously had relationships with actors Jason Statham and Billy Zane, rugby player Thom Evans, and personal trainer David McIntosh, who she was engaged to, and teased her attitude can seem like a man's when it comes to dating.

She said: "I'm a dude! I don't need anything else because I'm independent, so you might as well just change it up every couple of years and get a hottie!"
