The pair, played by Brooke Vincent and Nikki Patel, have become close in recent months but will fall out in the aftermath of Sophie's ill-fated wedding day, according to the Daily Star.
Sophie's friends and family gather to watch her tie the knot with Sian Powers (Sacha Parkinson) next month, but reports suggest that she doesn't go through with the ceremony as she is confused about her feelings for Amber.
When her relationship with Sian hits the rocks, it is thought that Sophie blames Amber for everything - unhappy that she messed with her head by kissing her on a recent night out.
The newspaper claims that Sophie soon ends up fighting with Amber on the street, before shouting that the shop girl is a secret lesbian in front of shocked residents.
A Coronation Street source commented: "[Amber] can't believe Sophie's dropped her in it. Amber is straight - she's not confused like Sophie's claiming. It creates a massive headache for her because her dad is far from happy."
Coronation Street's cast and crew filmed Sophie and Sian's wedding day scenes on location in Hale, Cheshire earlier this month.
