Life is wonderfully busy for Lin-Manuel Miranda. In addition to singing the updated Magic School Bus theme, he鈥檚 starring in the upcoming Mary Poppins sequel, writing music for the live-action Little Mermaid movie, working on the London production of Hamilton, and preparing for his return to the stage when the show opens in Puerto Rico in 2019. And things are about to get even more exciting for the star, as he and his wife, Vanessa Nadal, are expecting their second child.

Appearing at the 2017 London Evening Standard Theatre Awards in London on Sunday, December 3, Miranda and Nadal, a lawyer and scientist, posed on the red carpet together. After the Tony-winning composer shared a pic of himself and his lady on Twitter, a fan asked, 鈥渋s v..?鈥 To which an enthusiastic Miranda replied, 鈥淥h hell yeah.鈥

The 37-year-old, who鈥檚 already the proud dad of three-year-old Sebastian, added that his son is thrilled about becoming a big brother and can鈥檛 wait for the new arrival. 鈥淗e is so impatient for it,鈥 Miranda tweeted in response to another fan. 鈥淥nce, mid-tantrum, he cried, 鈥榃hen is mommy gonna HAAAATCH鈥'鈥 Too cute!

Last year, the Grammy winner told People that his 鈥渇avorite thing to do鈥 when he isn鈥檛 working is walking his dog and taking his kid to the park. 鈥淭hose are the two best things in my life,鈥 he said at the time. And one of those things is about to get even better, as he鈥檒l soon have two little ones to join him on park days!

Congratulations to the growing family!
