Tucci's tyke is here! Stanley Tucci and his wife Felicity Blunt have welcomed their first child together, his rep confirms to Us Weekly. The couple's son, Matteo Oliver, arrived in London on Sunday, Jan. 25.

"I believe he is mine. We are all thrilled to welcome him to this cold, cruel world," Tucci, 54, teased in a statement to Us. "We are all thrilled that he is here and healthy."

The Hunger Games: Mockingjay - Part 2 actor confirmed exclusively to Us in October that he and Blunt, Emily Blunt's sister, were expecting. (The Into the Woods actress and husband John Krasinski welcomed daughter Hazel in February 2014.)

"I'm very excited to be a dad. It's incredible. I'm most excited to have a baby with Felicity and for the baby to be healthy," he told Us at the Mario Batali Foundation Dinner at Del Posto in NYC on Oct. 19. He joked: "The sex is of no concern to me. The sex of the baby, that is."

This is the first child for Blunt, and the fourth little one for Tucci. The Devil Wears Prada star has three children with his late wife Kate, who died in 2009 from breast cancer.

Tucci and the London-based literary agent wed in 2012.
