The star, who has played lesbian temptress Sarah Barnes for the last four years, was overheard saying she was quitting at the end of the year at a London party, Digital Spy claims.
However, Lime Pictures - the company who makes the Chester-based soap - have refused to confirm Loui's departure.
The star has been in the show since 2005 and has been involved in some major storylines.
The most recent one saw her character have a one night stand with her father's girlfriend, before coming out as a lesbian and falling in love with fellow HCC student Lydia.
