Keri Russell is expanding her family.
The actress, 35, and husband Shane Deary are expecting their second child, her rep confirms to PEOPLE.
The new addition will join the couple’s son River, 4.
Russell, who most recently starred in Running Wilde, says she enjoys the balance between work and home that acting offers.
“I get to work really hard for three months but then I get to be home for four months where I get to put him to bed every night,” she has said.
