The actress – who plays Lauren Branning – is currently on maternity leave from the BBC One soap but she stopped by yesterday to introduce Ella to her colleagues.
Among those enjoying cuddles with Ella, six months, was actress Shona McGarty. Jacqueline shared an image of Shona and Ella to Instagram with the caption: "Ella got some serious cuddles today."
Jacqueline and Ella were joined on set by Jacqueline's fiancé, former TOWIE star Dan Osborne, and his one-year-old son Teddy.
Dan shared two further pictures of Teddy and Ella on set. In one, he's holding Teddy in the café with the caption: "Took Teddy to Albert Square today for some grub."
And in the second, look who is serving Teddy (while being held up by daddy!)
Jacqueline confirmed last November she would return to EastEnders after maternity leave, saying: "I know I will be coming back. I read somewhere I was taking a year out which isn't true. I definitely want to go back."
