Lin-Manuel Miranda and his wife, Vanessa Nadal, are expecting their second child. Nadal also showed off her growing baby bump at the London Evening Standard Theater Awards on Sunday night.

Vanessa Nadal Pregnant With Second Child

While at the event, Miranda was spotted wearing a dark blue suit while his wife wore a blue and gold floral dress. After walking on the red carpet, the Hamilton star shared a photo of himself with Nadal on social media.

One fan asked Miranda on Twitter if his wife was pregnant. "Oh hell yeah," replied the actor.

Miranda and Nadal tied the knot in 2010. They have a 3-year-old son named Sebastian. In June, Miranda paid tribute to his wife, who he first met when they were in high school, by getting a "V" tattoo.

Last year, Miranda also gave Nadal a touching shout out when he accepted his Tony Award.

"My wife's the reason why anything gets done. She nudges me towards promise by degrees. She is a perfect symphony of one. Our son is her most beautiful reprise," Miranda revealed.

Lin-Manuel Miranda Helps Puerto Rico's Disaster Relief

Meanwhile, other than his wife's pregnancy and the success of Hamilton, Miranda also made headlines after he showed support for the relief operations in Puerto Rico.

In September, he penned a touching letter detailing what the residents of Puerto Rico need after Hurricane Maria hit their homes.

"Puerto Ricans need supplies and resources just as badly as their fellow Americans in Texas and Florida, and this need is magnified by their geographic isolation from the mainland," wrote Miranda.

The "My Shot" singer also donated his money and time for the relief operations. He also released a song, titled "Almost Like Praying," on iTunes, especially for the Puerto Rico relief. The proceeds of the song were donated to the residents of the territory.

"Almost Like Praying" also debuted at number one on Billboard's Digital Song Sales chart. The track also gave the singer his first top 40 hit on the Billboard Hot 100 after it landed at number 20.

"By saying it's for Puerto Rico, that's all I had to do and everyone said yes without even hearing the song. I'm really proud that the lyrics are nothing more than the 78 towns of Puerto Rico. When Puerto Rico hears this song I want them to say 'Camila Cabello or Jennifer Lopez sang my town,'" said Miranda.
