The former teenage tearaway, played by Nicola Stapleton, is to make a comeback after 17 years away from Albert Square.
Ian Beale (Adam Woodyatt) will be stunned to discover Mandy working in a lap dancing club, before vowing to help her turn her life around, says The Sun.
"Nicola doesn't look like she has aged since she left. She looks amazing," a set source told the paper. "She found it a bit strange to film her first scenes in underwear and bikinis but she joked that she might as well 'jump straight back in'."
Mandy has been described as a "manipulative force of nature" and is expected to cause trouble for at least one Walford resident.
Meanwhile, Woodyatt has been filming scenes which see Ian approach a prostitute in North London. However, the businessman ends up being dragged to a police station, when the undercover policewoman reveals her warrant card.
