She may be a Hollywood starlet, but Hilary Duff will most certainly not be making diva demands as she prepares for her upcoming nuptials, according to sister Haylie. "We recently went through a bridezilla scenario with one of our friends, and she promised she would never!" Haylie told In Touch about her low-key little sis at the Tribeca Film Festival premiere of Earth Made of Glass, produced by pals Channing Tatum and Jenna Dewan, in New York on April 26. Luckily, Hilary has fellow actress Haylie's blessing in her choice of husband, hockey player Mike Comrie. "I think he is a wonderful person. He is perfect for her and makes her really happy," Haylie added of the pair, who were dating for over two years before their February engagement. Though her sister is planning to walk down the aisle, Haylie and her longtime love, actor Nick Zano, will not immediately follow suit. "We don’t really talk about it. We’re happy where we are with our dogs and our house," she said of saying no to "I do."
