This summer marks their one-year anniversary as an official item, and Hilary Duff and Mike Comrie are showing all of the signs of a couple who are very much in love.

Last night, the “So Yesterday” songstress and her New York Islanders hockey stud were spotted enjoying a romantic dinner out at the super-trendy Katsuya sushi restaurant in West Hollywood, California.

Duff looked conservative-yet-gorgeous in a black and grey layered top with a pair of grey Capri pants and black Christian Louboutin heels, while Comrie sported a black t-shirt and jeans complete with a wallet chain.

Earlier in the day, Hilary was spotted out and about in Beverly Hills visiting a medical building sporting a plaid top and grey pants as she text messaged on her mobile phone.

We think they make are really cute couple!!!
