Taking to Twitter to share her happy news, the overjoyed Eastenders star said: "Baby Ella Osborne was born yesterday. Thank you @DannyO and @Sarabro2 for everything. Amazing. She's perfect."
Ella's doting dad, TOWIE star Dan Osborne, was clearly over the moon about the new arrival as well, tweeting: "So so so so happy to tell you all!! Our baby girl Ella arrived yesterday evening, @jacquelineMjos done SO well, proud of you. I love you."
22-year-old mum Jacqueline was snapped recently looking a little tired and told fans and followers she couldn't wait to meet her baby, so we can only imagine how thrilled she is today.
Jacqueline's pregnancy was dogged by rumours of infidelity and mistrust, but the star remained composed and upbeat despite the speculation surrounding her relationship with Dan.
We hope the actress continues to share thoughts and snaps with us as she begins the next stage of her journey!
Congratulations Jacqueline!
