Actress Emily Deschanel is celebrating after giving birth to a son on Wednesday.

Little Henry Hornsby is the first child for the Bones star and her actor husband David Hornsby.

Deschanel's pal and Bones co-star T. J. Thyne took to his Twitter.com page to share the news, writing, "Congratulations Emily D!! Yay yay yay!!!"

The proud parents' new arrival came just four days before their first wedding anniversary - they married on September 25th in Los Angeles.
