Soleil Moon Frye has a son! The Punky Brewster alum gave birth to a baby boy, on Monday, Feb. 10, her rep confirms to Us Weekly.
"Our amazing baby boy was born yesterday," Frye tweeted on Tuesday, Feb. 11. "We are so excited for the newest addition to our family. Thank you for the love! Xo."
Her son was born in the early evening, and weighed over 9 lbs and measured 21 inches long. His name has not yet been released.
The 37-year-old actress and co-founder of moonfrye.com is already a mom to two daughters -- Poet, 8, and Jagger, 5 -- with her film and TV producer husband, Jason Goldberg.
"I can't believe that I'm going to have a boy!" Frye told Us back in October. "I'm still in crazy disbelief, it's crazy for me to say 'a boy.'"
The Let's Get This Party Started! author said she was hopeful that her daughters would lend her helping hand when their brother arrived.
"I hope that since Poet's eight and Jagger's five that they'll be little mommies. We don't have a nanny and everyone in our family chips in," she explained. "I never realized that as a mom I'd learn more from my kids then I could ever teach them. I thought I'd give them all this wisdom, and they're my biggest teachers. They're constantly inspiring me."
Shortly before welcoming her son, Frye tweeted that her due date had snuck up on her. "Been trying to get ready for this baby today," she wrote on Jan. 30. "Much harder with two little ones to run after."
But Frye was getting ready for the upcoming sleepless nights -- whether she liked it or not! "Wish I could sleep," she tweeted on Feb. 5. "Oh how the body prepares us for newborns."
