Forget snail-mailed baby announcements--new parents Hilary Duff and Mike Comrie can't stop sharing their baby joy with the world on Twitter.
The singer and actress, 24, and her hockey player husband, 31, welcomed a son, Luca Cruz Comrie, on March 20. (Duff used the social networking site to break the big news herself on Thursday.)
Three days after Luca's birth, Duff admitted her new reality hadn't quite sunk in just yet. "Wow I can't believe I have a baby!" she told her Twitter followers on Friday. "[Luca is] the most wonderful, sweet adorable baby!"
Proud papa Comrie chimed in on the virtual conversation, too. "Welcome to the world Luca Cruz Comrie," he tweeted. "Can't express my feelings for you right now!"
