Alyssa Milano welcomed son Milo Thomas Bugliari on Wednesday morning, with husband David Bugliari.
"Thank you for all the well wishes for my son Milo," Milano wrote on Twitter on Wednesday. "My heart has tripled in size. I love him more than all the leaves on all the trees."
The 38-year-old actress and David Bugliari, a 32-year-old talent agent, married in August 2009. Milo, who weighed 7 lbs. and was 19 inches long, is the first child for both.
"As fun as it was reading all of your gender predictions on Twitter, I'm really bad at keeping secrets and had to share (not to mention, I was bound to unintentionally slip at some point)," Milano wrote. "David and I are elated to announce that we are having a baby boy. We can't wait to meet him."
Milano recently appeared in the comedy "Hall Pass," which was directed by Bobby and Peter Farrelly.
She rose to fame with the comedy series "Who's the Boss?" and later went on to star in the shows "Charmed," the original "Melrose Place" and "My Name Is Earl." She also appeared in movies such as "Fear" and "Poison Ivy II" and inspired the face of Ariel in Disney's animated film "The Little Mermaid." In 2010, Milano starred in the short-lived series "Romantically Challenged."
Milano was married to songwriter Cinjun Tate between January and November of 1999. They have no children.
