A Bones baby!

Emily Deschanel and husband David Hornsby welcomed son Henry on Wednesday, her rep confirms to Us Weekly.

It's the first child for the Bones actress, 34, and the It's Always Sunny and Philadelphia actor, who celebrate their one-year wedding anniversary Sept. 25.

A staunch vegan, Deschanel kept her no-meat, no-dairy diet throughout her pregnancy.

"I still have to defend myself because people don't understand it," she told Ladies Home Journal. "As a pregnant woman especially, people will say to me, 'You must eat meat and dairy.'"

Emily's little sister is fellow actress and New Girl star Zooey Deschanel, who Tweeted her excitement soon after the pregnancy announcement in late March.

"I am super excited to be an aunt!" Zooey, 31, wrote.
