The Carla Connor actress will, however, continue to work alongside the sound technician on the ITV soap's set, reports The Sun.
She had taken four months away from Corrie between June and October to enjoy a "nice holiday" with Huckett and the pair's 3-year-old daughter Daisy Mae.
However, an insider suggested they have now split, claiming: "There haven't been any big rows. It's been a difficult decision, especially because they have so many joint friends on the set.
"It's not an ideal situation coming face-to-face with your ex-fiancé every day. But they're determined to stay good mates and want to make it very clear that there isn't anyone else involved."
Alison King's return to work was confirmed by Corrie last week, while on-screen boyfriend Chris Gascoyne was spotted collecting a script from the Manchester studio at the end of September.
The 39-year-old had been engaged to Huckett since last September.
