The couple is already parents to 13-month-old daughter Autumn James. Hewitt married Hallisay, who is also an actor (he appeared with his wife on the Lifetime show The Client List), five days before giving birth to Autumn in November 2013.
In a recent appearance on Jimmy Kimmel Live!, the former Party of Five star discussed motherhood. "It's really great," she said. "She smiles, she's walking, she's waddling like a little penguin, she's an overachiever just like me. It's terrifying. There's gates everywhere that I trip over."
Clearly Hewitt, who currently stars on Criminal Minds, also enjoyed being pregnant as she designed a maternity wear line for A Pea in the Pod in 2013. She gave InStyle some tips last year on dressing up the bump. “What I’ve really realized is that the bigger you get, the better to go a little bit tighter in the clothing because there is a purpose for it,” she said. “Otherwise you end up looking like you’re in this gigantic tent and you’re this floating tiny head with this big body,” she laughed.
