Natalie Cassidy has given birth to a baby girl.
The 'EastEnders' star - who plays Sonia Fowler in the BBC One show - welcomed daughter Joanie with her fiancé Marc Humphreys.
She wrote: "@cameramarc and I introduce Joanie Elizabeth Cassidy-Humphreys... We are all so in love! (sic)"
The 33-year-old actress - who also has five-year-old daughter Eliza with her ex-partner Adam Cottrell - announced her pregnancy in February this year.
Taking to social media at the time, she wrote: "Evening all... Time to let everybody know that @cameramarc and I are having a baby in the summer. The three musketeers become four (sic)."
The happy couple got engaged in October 2015, much to the delight of their family and friends.
A source said: "Family and friends are thrilled for Natalie and have been buying gifts for them to celebrate."
Whilst a spokeswoman for 'EastEnders' added: "She is really happy."
And Natalie previously revealed she reconciled with her abusive ex-partner Adam for a brief time as she tried to make it work for the sake of their child.
She said: "It was my decision. I'm really glad I gave it another chance. When kids are involved you almost have to. I can always say to Eliza, 'Mummy tried, but it didn't work out.'"
The pair started dating in 2010 and got engaged soon after. He was charged with assaulting her and received 120 hours of community service.
