Hilary Duff "surprised" by proposal

Hilary Duff was "completely surprised" by her NHL star boyfriend Mike Comrie's proposal, according to her sister Haylie.

The couple, who have been dating for over two years, were on holiday in Hawaii when Comrie asked Hilary for her hand in marriage.

The older of the two siblings told People: "I don't think that happens all the time. I think most of the time people figure it out or have some idea that it's going to happen, and I think it's great he was able to do a surprise like that for her."

Though Haylie did not mention the specifics of the circumstances surrounding Comrie's proposal, she did say that it was "very romantic".

The 25-year-old added that she definitely approves of Hilary's fiancé, saying: "I adore him... He's wonderful."
