The charmer's comeback storyline begins when Audrey (Sue Nicholls) and her daughter Gail (Helen Worth) come face-to-face with him at a country pub away from Weatherfield, according to the Daily Star.
A shocked Lewis (Nigel Havers) is expected to panic when the pair confront him, before coming up with an unlikely cover story.
Lewis is quoted as saying: "I think you are mistaken. I'm Lewis's twin. We're always mistaken for each other."
When it's clear that Audrey and Gail don't believe him, Lewis apparently begs them not to call the police. However, he later makes a shocking decision as he finally returns to Weatherfield to face the music.
Lewis reportedly causes a stir as he walks back into The Rovers, prompting furious Deirdre Barlow (Anne Kirkbride) to punch him in the face - still livid after he wooed her for his own financial gain at the bookies.
The rogue also visits Peter Barlow (Chris Gascoyne) to apologise for scamming him.
Show bosses announced Lewis's return late last year, but storyline details had been kept under wraps until now.
Coronation Street fans will also be left to wonder whether Lewis can win back Audrey when his return scenes air in February.
