"My husband and I are happy to announce the arrival of our baby girl, Victoria Milani," Castillo announced on Twitter. "We are in LOVE."
Victoria was born on May 29, and weighed in at 7 lbs., 2 oz., and measured 20 inches long. The little one's little name pays homage to her dad's Hawaiian roots.
Castillo announced her pregnancy in December 2013 -- and at the time, Castillo was certain she'd be having a boy.
"Shane and I were actually surprised it was a girl!" Castillo shared with Soaps In Depth. "We were certain it was a boy. But we're both completely thrilled. I'm one of three girls and I have two nieces, no boys. So our families weren't surprised at all. Everyone is very excited."
UPDATE (July 11):
Castillo announced on Twitter that she's preparing to head back to work.
"18 days till I go back to work and I cannot wait!" Castillo wrote on July 10. "Miss my GH fam so much."
The actress will make her on-screen return on Thursday, August 21. Castillo joined GH in September 2012.
