Hilary Duff may be a crazy fan when she’s cheering for her hockey-player fiancé Mike Comrie but when it comes to wedding planning, the actress is a lot more calm, people.com reports.

“She’s really relaxed and wants something comfortable and great,” big sister Haylie Duff said Monday at the Tribeca Film Festival premiere of the documentary Earth Made of Glass. “She’s just so excited to be engaged.”

Comrie, 29, who plays for the Edmonton Oilers, proposed to Hilary, 22, over Christmas in Hawaii. Four months later, she and her sister are still in the early stages of planning the nuptials.
