"I have a very big announcement," the Punky Brewster star said. "We have a newest addition to the family here."
Frye, 37, and her husband, Punk'd executive producer Jason Goldberg, wed in 1998. They are already parents to Jagger, 5, and Poet, 8. "Poet and Jagger are so excited," Frye added. "I'm so excited I can actually touch my belly now, I've been hiding it for so long."
