Emma Roberts and Evan Peters ''didn't get along'' when they first met.

The 22-year-old actress was arrested and released without charge after a domestic violence incident involving her boyfriend in Montreal, Canada, last week, and in an interview she gave before the arrest, Emma revealed they didn't hit it off straight away.

She told NYLON magazine: ''We first met at a dinner party, and then we worked together on a movie ['Adult World'], which we did not date during. We didn't get along, actually - he wouldn't speak to me. But it turned out that we both liked each other, so months later, we started dating, which worked out for the best.''

When asked at the time about her good girl image, Emma said: ''I can't say I'm never going to mess up, but if I do, I'll definitely be very sorry.''

Despite the incident, Evan, 26, has no plans to press charges and the couple, who friends say are ''crazy in love'' will stay together.

A source close to the 'We're The Millers' star - who is Oscar-winner Julia Roberts' niece - said: ''Emma is very dramatic. They will not break up. When they are good, they are crazy in love.''

But the insider said the couple's violent altercation on July 7 went ''way out of control'', explaining that Emma can get ''wound up''.

Another insider close to the actress insisted that the couple, who began dating a year ago, are ''inseparable''.

The source said: ''They're a couple young kids. Their romance is pretty extreme. They just behave in a way that's very passionate.''

A spokesperson for Emma said: ''It was an unfortunate incident and misunderstanding. Ms. Roberts was released after questioning and the couple are working together to move past it.''
