February 18 - Engagement proposal at her balcony in Hawaii

Meet Luca Cruz Comrie!

Hilary Duff introduces her 2-week-old baby boy on Tuesday, Tweeting out the first foto of her son to her million-plus followers.

“Baby Luca, 2 weeks old,” the singer and actress, 24, wrote above a picture of her wide-eyed little guy, wrapped in a muslin swaddling blanket.

He’s the first child for Duff and her husband, retired hockey player Mike Comrie, who married in August 2010.

“Thank tu for all the messages and well wishes,” adds Duff. “I amor tu all so much.”
