Kacey Ainsworth would only return to 'EastEnders' if she could "snog Danny Dyer".
The 49-year-old actress played Little Mo Slater in the BBC One soap from 2000 to 2006 and she is keen to get up close and personal with the 'Football Factory' star's alter-ego, Queen Vic landlord Mick Carter, if she does step foot in Walford again.
She said: "I think I'll have to have a rider. I'll only go back if I can get behind the bar of the Queen Vic and snog Danny Dyer."
Kacey's on-screen sister Jessie Wallace (Kat Moon) recently returned to Albert Square, but she is "so busy" shooting detective drama 'Grantchester', in which she portrays Cathy Keating, the star doubts Mo will be downing drinks with Kat in the Vic anytime soon.
Speaking on 'Loose Women', Kacey added: "She was such a great character and I'm still in contact with my on-screen sisters. We are really close.
"We've talked in the past about going back.
"The writers on 'EastEnders' are amazing and brilliant - and my old boss is there now.
"But I'm so busy with 'Grantchester' and filming all summer, and 'Grantchester' is like a global programme now so I'm also filming in America.
"So it would have to be logistically right. And I loved her so much, she was such a brilliant character that I wouldn't want to dilute her by going back with something."
In April, Kacey admitted she missed shooting 'EastEnders' "every day", despite the filming schedule being "crushing".
She said: "I miss doing it every day and working on something where you know everyone from the crew to the tea lady.
"The schedule on the soap can be crushing but I loved her and people still call me Mo in the street. It's lovely to have created a character who people not only identified with but also took to their hearts."
