It looks like the cat's outta the bag!
The actor dished that his wife gave birth to the couple's second daughter, but didn't divulge any details yet on the baby girl's name.
"Two [kids] under two is tough," he told the comedian before adding, "Yeah, a lot of estrogen. It's like an American Girl doll took a s--t on my life."
Earlier last month, Ryan let it slip that his little bundle of joy was a female when he tweeted, "The mobile above my daughter's crib is just a whole bunch of NuvaRings. So she remembers how lucky she is."
The actor and actress recently welcomed their second child into the world but have remained notoriously private about any details surrounding the arrival.
Back in January 2015, the well-known twosome became parents for the first time after the Sisterhood of the Traveling Pants and Gossip Girl star gave birth to daughter James.
Congratulations once again to the proud new parents!
