Jenna Dewan and Steve Kazee have welcomed their first child together.

The Step Up actress confirmed the happy news on Instagram on Tuesday night, as she also shared their newborn son's name. "And just like that, our hearts exploded into all of eternity and beyond," she wrote on Instagram. "Welcome to the world you little angel!" In the caption, she also revealed the baby boy was named Callum Michael Rebel Kazee - and he had been born on March 6. The couple's happy news comes a few weeks after they revealed that they had gotten engaged. The now-mum-of-two shared the news with her fans, as she posted a photo of the two of them sharing a kiss. “A lifetime to love and grow with you…you have my heart," she captioned the post, adding a heart emoji. Kazee shared the same photo on his own Instagram account to confirm the happy news, quoting Water Liars' Let It Breathe in the caption. “When you wake in the morning I will kiss your face with a smile no one has ever seen,” he wrote. “When you wake in the morning I will kiss your eyes and say it’s you I have loved all these years.” In September 2019, the couple announced that they are expecting their first child together. “We are beyond overjoyed and couldn’t be happier to be expanding our family," they said in a statement to PEOPLE at the time.
