But, despite her EastEnders role being hailed by all, Kacey Ainsworth is in no hurry to return to Walford as she is enjoying playing diverse roles, very different from the Slater family favourite.
Speaking exclusively to Express.co.uk, the actress opened up about life after the BBC soap, if she had any regrets on bidding it farewell and her latest project, The Worst Witch.
When asked about Little Mo's exit, Kacey commented: "I went off and had my children, came back and started playing deliberately different roles from her.
"She was a lovely creation and I loved playing her. Now I look back on it, I think I did a good job there."

Kacey continued: "But, I've really enjoyed the diversity I’ve had since having the kids, from Grantchester to Call The Midwife, and a British thriller which is coming out.
"I’ve deliberately picked roles that are diverse as that is what I enjoy. Little Mo was a real move away from parts I’d played before – it’s nice to have change."
Asked if she regretted going, she went on: "No, not at all… It’s been brilliant since I left – I’ve done so many different jobs.
"A lot of the time it is not as high profile in terms of your constantly on front covers, but it is about the work for me, not the level of visibility."
Meanwhile, Kacey's newest role is a long way away from Albert Square as Miss Gullet in CBBC's adaptation of The Worst Witch.

She said of taking the part: "I read the books when I was younger and the chance to work with magic, kids, frogs, flying, CGI – it was all too much to say no to and the budget’s fantastic."
Despite remaining secretive about Miss Gullet, Kacey added: "The great thing is she’s an original character, it’s always lovely to get someone you can create from the off.
"However, she’s not as she seems – I don’t want to give anything away."
The Worst Witch airs Wednesdays at 4.30pm on CBBC.
