Nasty Nick, played by John Altman, was thought to have died from a heroin overdose in March and Dot was even seen crying over his coffin at his funeral.
However, in last night's episode of the BBC One soap, the notorious villain's voice was heard on his son Charlie's phone...
Speaking about his return to EastEnders following a five-year break, John said he is looking forward to working with his "dear old Ma", played by June Brown.
He added: "I'm very pleased and much looking forward to coming back to EastEnders.
"With the promise of some hard-hitting and gritty storylines I'm sure residents of Albert Square will be none too pleased to see Nick Cotton back."
It has not been revealed exactly how Nick's return to Walford will be explained, however executive producer Dominic Treadwell-Collins feels it is the perfect time to bring him back.
"As we approach EastEnders' 30th anniversary, it's only fitting that our original bad boy, and soap's most iconic villain, returns to cause more troubled for his Ma."
We can't wait!
