Miranda Kerr is a mom for the second time!
Miranda Kerr and husband Evan Spiegel have welcomed their first child together.
The couple named their newborn boy Hart Kerr Spiegel and he was born at 11.53pm. The couple, who married a year ago, have welcomed their first child together, a baby boy called Hart.
"Words can not explain how happy we are to welcome our attractive son into our family".
Kerr has one other child, Flynn who is 7-years-old, with actor Orlando Bloom.
Flynn is no doubt overjoyed about his new big brother role.
In July 2016, the couple announced that they were set to get married after revealing that they were engaged on social media.
Miranda and Evan confirmed the happy news to People in a statement, saying, "Words can not explain how happy we are to welcome our handsome son into our family".
Congratulations Evan and Miranda (and you too, Flynn)!
