Seth Meyers is a dad!
The 42-year-old "Late Night" host and his wife, Alexi Ashe, welcomed their first child -- a baby boy -- on Sunday, March 27, Us Weekly reports. They have not yet announced the name of their new addition.
The couple leaked news of Alexi's pregnancy while attending a gala at the Natural History Museum in New York last fall.
"They are so thrilled to become parents," a source told Us at the time.
"Everyone gives so much advice. There are a lot of 'experts' out there, and as much as you think, 'I'm going to follow what this person says, I'm going to follow what that person says, I'm going to read this book and have this birth plan,'" she replied. "It's not up to you, dude. Let it go. Don't worry about it."
Letting a laugh escape, she added, "You're going to struggle. It's going to suck just like for everyone else."
Seth took Jennifer's words of wisdom in stride, saying, "OK, so based on what you told me, I can go back to my wife, who's just been piling up stacks of books for me, and say, 'This doesn't matter.'"
Jennifer backpeddled quickly. "Do not say that!" she warned with another laugh.
Seth and Alexi, a human rights lawyer, tied the knot on Martha's Vineyard in 2013, joined by a slew of Meyers' friends from "Saturday Night Live."
And while Alexi seemed to have relished the wedding planning process - especially the part that involved being fit for a Carolina Herrera gown - she narrowly avoided a major nuptial mishap when she came down with food poisoning the night before the big day.
"In a testament to my wife's will and my wife's strength, she got herself pumped full of fluids, and she rallied and made it to the ceremony" Seth told Us. "When she walked out in her Herrera wedding dress, she looked more beautiful than I had ever seen her look."
After breaking over the Easter holiday, "Late Night With Seth Meyers" returns to NBC on Tuesday, March 29.
