Young actress Emma Roberts is determined to challenge Hollywood's marriage laws when she finds her Mr. Right, because when she weds, she'll wed for life.

The Scream 4 star's parents - actor Eric Roberts and mum Kelly Cunningham - split when she was a child and her famous aunt Julia has one failed marriage behind her, so the 22 year old knows just how difficult it is to keep a relationship together in the spotlight.

However, she insists she'll only get married and start a family when she knows she's found the perfect guy.

Roberts, who is currently working on her romance with actor Evan Peters after she was accused of attacking him in a Canadian hotel last month (Jul13), tells Nylon magazine, "I've been with people in the past who lie about what they're doing or whom they're with, and you always find out about it.

"I've grown up in a business where we're taught to think that relationships don't last, and that people are supposed to be married a bunch of times. But I come from the school of getting married once... Everyone kind of rolls their eyes at me, but I still believe in the romantic movie outcome."
