Chatting with co-host Jenny McCarthy, Frye unwrapped a small box containing a pair of tiny blue shoes: It's a boy!
"I'm in a little bit of denial," said Frye, who has two daughters, Poet Sienna Rose, 8, and Jagger Joseph Blue, 5, with her husband, producer Jason Goldberg. "I can't imagine a penis growing inside of me, so I keep saying, 'I think we know, but I'm not sure.'"
Frye said Poet and Jagger seem unfazed by the idea of a little brother.
"My girls still don't completely believe it," she joked. "They're like, if it's a boy we're still dressing him up."
The baby boy is due in February 2014.
