Hilary Duff & Mike Comrie: Sweet Smooches

Hilary Duff hasn't been shy throughout her first pregnancy, and now her hockey star husband Mike Comrie is getting in on the action too!

In an intimate photo uploaded as her Twitter profile picture, Duff, 24, is sitting in a chair, patting her baby bump, while tilting her head back to smooch with her newly retired hubby Mike Comrie, 31.

"Glad you guys like my new pic! Much love to all you guys," the Lizzie McGuire alum tweeted to her 900,000 followers.

The pair, who have been married for 18 months, are expecting a baby boy in March.

On Monday, it was announced that Comrie is retiring from the NHL.

"To have made the lasting friendships I enjoy today with so many of my former teammates is something that will stay with me for the rest of my life," he said in a statement. "It's the reward that has made all the hard work, the trades, the moves and the surgeries worthwhile."
