The singer-songwriter is pregnant and expecting her second child with husband Rollie Gaalswyk, she revealed Sunday on social media.
Smith announced the happy news on Mother’s Day holiday, sharing a throwback photo of herself with her now-21-month-old son Thomas Miles as a newborn and a second of Thomas now, wearing a “WORLD’S BEST BROTHER” shirt.
“Almost 2 years ago, this sweet boy made me a mother and showed me a new love I have never known,” Smith captioned the images, which were shot by photographer Kelly Christine. “This November, we get to do it all over again and I’m pretty sure my heart my burst. ”
“Oh so grateful this Mother’s Day — for my beautiful mom, for sweet little Tom, and the tiny miracle on its way … ” added the “Like I’m Gonna Lose You” singer.

Smith — who is on her Starfire Tour through the end of September — welcomed Thomas in August 2016, writing on Instagram following his birth, “One month ago, he finally showed up and I kissed the top of his head and held him in my arms and I was everything I was for the last time.”
She added, “I was new. He is love I’ve never known — beauty I have never seen — like someone pulled a blanket off the sun. He’s changed everything.”

The musician told PEOPLE in January that her new song “This Town Is Killing Me” comes from “an intimate place between the singer and the microphone.”
“I wanted to capture the loneliness that can live there sometimes,” said the Minnesota native.
Smith’s debut studio album Starfire is available now on amazon.com.
