Felicity Blunt gave birth to her first son on Monday.
This is her first child with her husband, Stanley Tucci.
Felicity Blunt married the Hunger Games star back in 2012.
Felicity Blunt is the sister of actress Emily Blunt.
Lucky for their new son, who they named Matteo Oliver, Emily Blunt already provided a playmate for him, daughter Hazel.
She just had her first child with husband John Krasinski early in 2014. It will be fun for Emily and Felicity Blunt to watch their two babies grow up together!
Stanley Tucci said of the arrival of his son with Felicity Blunt, "I believe he is mine. We are all thrilled to welcome him to this cold, cruel world."
Then more seriously, he added, "We are all thrilled that he is here and healthy."
Felicity Blunt's son will join an already big family! Stanley Tucci is already a father to Camilla, 12, and twins Nicolo and Isabel, 14, who he had with his late wife, Kate.
Kate died of breast cancer in 2009.
Stanley Tucci annoucned that Felicity Blunt was expecting on an episode of Access Hollywood Live last October. He was there to discuss his cookbook, The Tucci Table, but he took the time to let the world know that he was going to be a dad again.
"My wife Felicity is pregnant. She's due at some point," Stanley said.
That, I'm sure, was non-specific for the sake of Felicity Blunt, and isn't that just his style?
Congratulations to Felicity Blunt and Stanley Tucci on the addition to their growing brood! What do you think of Stanley Tucci starting over with a baby when his youngest is 12?
