Reports from the US have claimed that Blake gave birth to her second child in New York at the end of September - meaning congratulations are in order for the Gossip Girl star and husband Ryan.
According to People, a source confirmed the arrival of Blake and Ryan's new addition, but no further details surrounding the birth have yet been given - including the baby's name and sex.
The couple, who are known for being notoriously private, have not yet commented.
Reports first surfaced that Blake was pregnant again in April, earlier this year. Neither Blake or Ryan confirmed the rumours at the time, but Blake was seen sporting a baby bump at Cannes Film Festival a month later. A source had told E! News: "They are very excited. Blake always wanted two or three kids."
She and Ryan are already parents to their daughter James, who turns two in December.
Blake gave birth to James on 16 December 2015, and Ryan confirmed her arrival several weeks later during interviews where he opened up about fatherhood. However, he didn't confirm her exact birth date until James' first birthday, when marking the moment on Twitter.
He tweeted: "Happy birthday to my baby girl! Sad I lost my virginity. But thankful I have a daughter."
