They were embroiled in a bloody fight just six months ago but Emma Roberts and Evan Peters are moving past the drama with a trip down the aisle.

The couple, below, who star opposite each other in American Horror Story, became engaged over the Christmas period in New York, where Peters proposed to his lady love with a pink, gold and diamond ring.

Roberts, 22, and Peters, 26 first met on the set of the film Adult World and he said they were instantly attracted to each other, even though they didn't get together until 2012.

"I think we both had crushes on each other but we didn't know it. As soon as the movie was done we started hanging out and everything was perfect," Peters gushed.

"She's amazing. She's so much fun. She has a great laugh, smile, she's a great kisser. And she's gorgeous."

However, the path of love has not always been smooth for the couple.

In July last year Roberts - niece of actress Julia Roberts - was arrested when the duo had a fight in Montreal, Canada, which left Peters with a bloody nose and a bite mark, and her with bruised legs.

The police intervened after somebody else in their hotel called for help but Roberts was released without charge.

The couple didn't break up over the incident and friends later claimed they have a "pretty extreme" relationship but were "crazy in love" with each other.

A spokesperson for Roberts said at the time: "It was an unfortunate incident and misunderstanding.

"Ms Roberts was released after questioning and the couple are working together to move past it."
