Miranda Kerr and Evan Spiegel have officially welcomed their first child together overnight. The former Victoria's Secret model and Snapchat founder have had a son, whom they have named Hart, seemingly after Spiegel's grandfather. 

The pair announced the happy news to People saying, "Words cannot explain how happy we are to welcome our beautiful son into our family. Miranda is doing well and Flynn is excited to be a big brother. Thank you for the kind words and wishes during this very special time."

This is Spiegel's first child and Kerr's second son — she is also mum to Flynn, 7, with her ex-husband Orlando Bloom.

The pair first announced the news back in November of 2017, and Miranda has been active on Instagram throughout the pregnancy promoting her organic skincare line, Kora Organics.
