Last month, tabloid reports suggested that physiotherapist Jenna (Krissi Bohn) will become a new love interest for Sophie Webster (Brooke Vincent) while continuing to help the teenager get her life back to normal after she was injured in a serious road accident.
Speaking on This Morning today (November 19), Charles hinted that Lloyd will be surprised but ultimately accepting of Jenna's upcoming relationship.
Charles confirmed: "She is going to have a relationship with someone on the street, and it's going to be very shocking for Lloyd!
"How's he going to cope? I think Lloyd's a cool cat, really. I think he just wants her to be happy. But there's going to be a lot of tensions."
Lloyd only discovered Jenna's existence two months ago thanks to a chance meeting with old flame Mandy (Pamela Nomvete), and Charles told This Morning hosts Phillip Schofield and Holly Willoughby that the storyline was partly his idea.
He said: "I did suggest to them just before the 50th [anniversary] that there'd never been a black family on Coronation Street and after 50 years, it would be quite nice to have one. I'm obviously a black character so they could build it around me, and they went away and came back with this story."
Charles also admitted that he will have to take another break from Coronation Street for his role in Red Dwarf if the popular sitcom is recommissioned. He was previously absent from the cobbles for the first half of this year due to his other filming commitments.
He said: "We certainly would like to do [another series]. I think they want to do it, so it should happen. Coronation Street are going to have to let me off for a little while longer.
"We'll see if it works. If it doesn't work, it doesn't work. If things are meant to be, they happen. I love playing Lloyd, I wouldn't want to stop playing him.
"I was really rejuvenated when I went back to Coronation Street, because I'd had a little break. Coronation Street is one of those things where it doesn't have a wrap party, it just keeps going on and on like a machine. It was good to go away, do something else, recharge your batteries and then come back revitalised."
Coronation Street continues tonight (November 19) at 7.30pm and 8.30pm on ITV1.
