Hilary Duff is "relaxed" about her wedding plans.

The singer-and-actress - whose hockey player boyfriend Mike Comrie proposed in December - is making the most of being engaged and is keeping calm ahead of her big day.

Hilary's sister Haylie Duff revealed: "She's really relaxed and wants something comfortable and great. She's just so excited to be engaged.

"We've started talking about the wedding stuff, but she's still just really happy in this sort of phase. It'll be a while, but it's fun to talk about it and think about it."

Haylie is happy that her sister is staying relaxed about her impending nuptials and hasn't turned into "a bridezilla".

She added to People magazine: "She's just not the type. One of my other best friends got married and was a complete bridezilla, so I'm not getting the signs from Hilary that that's the case."

Mike proposed to Hilary while they were holidaying in Hawaii over the festive period.

The couple have been dating for over two years.
