The actress recently filmed her final scenes as Heather Trott, who meets a tragic end later this month as she is killed by troubled teen Ben Mitchell (Joshua Pascoe).
Fergison reflected on her Walford exit while speaking to Red Carpet News TV at the season two premiere of House of Anubis yesterday (March 11), confirming that her fellow cast members threw her a leaving party.
"I've actually finished at EastEnders now - I finished filming about three weeks ago," she explained. "You'll see the results of that on the 19th.
"The send-off was very emotional and we had a great party. It was lovely to see everybody. I'm just going to miss it, because it's a great family show. But onwards and upwards."
She added: "Working with Linda Henry who plays Shirley has been an amazing experience, [she's] a very close friend. I've made some really good friends.
"Keep watching and thank you very much for all of your support over the years. Keep an eye out for other stuff that I do."
Fergison's EastEnders departure was announced last September.
