Meet Nicole Richie and Joel Madden's look-alike kids! Couple's rarely seen daughter Harlow, 16, and son Sparrow, 14, make red carpet debut at premiere of Don't Tell Mom the Babysitter's Dead

Nicole Richie and Joel Madden's rarely seen kids made their red carpet debut on Tuesday, as they supported their mom at the premiere of her film Don't Tell Mom the Babysitter's Dead in Los Angeles. 

The Simple Life star, 42, and the Good Charlotte rocker, 45, were joined by daughter Harlow, 16, and son Sparrow, 14, at the event, which took place at The Grove.

Sofia Richie's older sister wowed as she stood next to her teenagers in a chic black mini dress with a chunky gold neckline.
