Adam Woodyatt, who came up with the idea for a Midlands based event, Pam St Clement and Michelle Collins are expected to be at the Family Fun Day in the Jaguar Exhibition Hall at the Ricoh Arena on February 28th.
Ricoh Arena CEO Daniel Gidney said to BBC Coventry & Warwickshire: "We're delighted to get involved. "There's going to be some indoor fair equipment, some performances by local bands and the headline is going to be some celebrity signings and question and answer sessions from key members of the Eastenders cast.
"Part of the reason the Ricoh was built was for community spirit and this is one of the things we're proud to do. We urge people to come down and support the day and raise as much as we can."
Ticket details for thev event are still to be announced but prices for the day which starts at 10.30am are expected to be £10 for adults and £5 for children.
