Christopher Backus and Mira Sorvino

Mira Sorvino is expecting her third child with husband Christopher Backus.

"We are overjoyed at the thought of welcoming a new addition to the family," the parents-to-be told People. "With each child the love in our hearts has expanded beyond what we ever imagined was possible."

Sorvino, who won an Oscar for 1995's Mighty Aphrodite, and Backus, an actor, are already parents to Mattea, 4, and Johnny, 2. The couple married in 2004.

Sorvino was most recently seen in last month's NBC miniseries The Last Templar.
