Jennifer Love Hewitt is "excited about expanding" her family.
The 35-year-old actress, who announced she's expecting her second child with husband Brian Hallisay earlier this month, "can't wait" to give their 14-month-old daughter, Autumn, a sibling.
A source close the 'Criminal Minds' star said: "Jennifer is almost four months pregnant and doing great. She's head over heels for her daughter, Autumn, and can't wait for her to have a sibling.
"They are loving being a family and excited about expanding. Jennifer knows having two children under two is going to be a lot of work, but she loves the idea of having her kids be close in age. Being a mom is the most important thing to her and she's thrilled about being pregnant again."
The brunette beauty, who married 'Revenge' star Brian in a secret ceremony in 2013, brings Autumn to work with her every day, as she wants to spend as much time as possible with her before she gives birth.
The insider told E! News: "When Jennifer has been working on 'Criminal Minds,' a nanny brings Autumn to the set every day. They play in her trailer while Jennifer is filming and then when she has breaks, she gets to see the baby.
"Jennifer and Brian are often at home with Autumn and spend as little time away from her as possible."
