Posting the photo to Twitter, Jacqueline said: "Me and mini me! #babylove."
Aww! So cute. The snap certainly left fans commenting that Ella looks the spitting image of her famous actress mother.
Jacqueline welcomed Ella with fiancé Dan Osborne last year, and is still on maternity leave from her role as Lauren in 'Enders.
Talking about her character Lauren, Jacqueline recently told Loose Women: "I get so bored when she's happy because it's boring! I like crying, I like screaming. I get so excited when I read there's a punch. I'm like, Please let me do it! I get so excited."
Lauren's exit was aired in February last year, when she and boyfriend Peter Beale decided to move to New Zealand as they prepared to take their first steps into parenthood.
Lauren made a brief return to Walford in September for her father Max Branning's murder trial, where she also gave birth to son Louie.
Jacqueline was asked if she's stayed in touch with co-star Ben Hardy, who played Peter. He quit the soap and is now in Hollywood working on the new X-Men movie.
"No, not really," she told Loose Women. "It's really weird because when you're in there, in the whole EastEnders bubble, you're best friends with these people. As soon as you come out, you get back to your normal life. It's kind of sad because when I had my last scenes with him, I thought 'I will probably never see you again', and I haven't."
