Evening Standard Theatre Awards 2017 - LondonThe Ham Fam is growing: Lin-Manuel Miranda revealed that he and wife Vanessa Nadal are expecting their second child.

The performer made the announcement on the sly on social media over the weekend, sharing a photo from the red carpet of the London Evening Standard Theatre Awards, which he attended alongside Nadal. Miranda added a not-so-subtle emoji to direct fans to take a closer look at his wife, who appeared to be sporting a growing baby bump in the image.

One of the "Hamilton" star's followers responded by asking if Nadal was indeed pregnant, to which Miranda had a hilarious, succinct reply.

"Oh hell yeah," the performer wrote.

The couple, who wed in 2010, already has a 3-year-old son, Sebastian. And according to Miranda, the little guy can't wait to be a big brother.

"He is so impatient for it," Miranda said in response to a fan query about Sebastian's excitement. "Once, mid-tantrum, he cried, "When is mommy gonna HAAAATCH..."

"When is mommy gonna hatch" might be the funniest/cutest sibling-to-be question we've ever heard. Miranda declined to reveal when Nadal is due, though, so it looks like we'll be not-so-patiently waiting along with Sebastian for more Baby #2 news.

Congrats to the soon-to-be family of four!
