Kelly Brook's former fiance David McIntosh has branded her a ''bully''.

The bodybuilder and former marine - who dated Kelly on and off for over a year - has spoken out to claim she mentally abused him and is ''incapable'' of having a normal relationship.

He said: ''Bullying isn't about physical strength. It's mental.

''I'm a hard man but when I love someone I let my guard down and people exploit that.''

The 29-year-old star got engaged to Kelly, 35, in 2014 after a whirlwind 11 week relationship which even saw them move to Los Angeles together.

However, just six months later they called time on their romance before appearing to get back together on numerous occasions.

David told The Sun on Sunday newspaper: ''She was everything that I wanted.

''And then it turned sour. That's what's so shocking. She's a beautiful woman but she can be nasty too.''

The former Gladiator claims the 'One Big Happy' actress began abusing him just three weeks into their relationship when she dumped him after receiving a text message from her ex-boyfriend Danny Cipriani telling her not to be with him.

And he's now confessed he feels ''sorry'' for Kelly's new boyfriend Jeremy Parisi.

David added: ''I don't know what she's looking for. I think she's incapable of having a normal relationship. I feel sorry for Jeremy. He looks a decent lad.''
