It's a boy for Stanley Tucci.

The "Hunger Games" star and wife Felicity Blunt welcomed son Matteo Oliver in London on Jan. 25, he confirmed in a statement obtained by People.

"I believe he is mine. We are all thrilled to welcome him to this cold, cruel world," he joked, adding, "We are all thrilled that he is here and healthy."

This is the first child for the couple and the fourth for Tucci, who is also a dad to twins Nicolo and Isabel, 14, and daughter Camilla, 12, with his late first wife, Kate.

The 54-year-old actor tied the knot with Blunt, the sister of actress Emily Blunt, in 2012. He confirmed in October that they were expecting their first child together.
